By definition, a rectangle is a parallelogram because its pairs of opposite sides are parallel. A rectangle also has the special characteristic that all of its angles are right angles; all four of its angles are congruent.
Besides, how many congruent angles does a rectangle have?
Opposite sides of a rectangle are the same length (congruent). The angles of a rectangle are all congruent (the same size and measure.) Remember that a 90 degree angle is called a "right angle." So, a rectangle has four right angles. Opposite angles of a rectangle are congruent.
Secondly, what shape has 4 congruent sides and no right angles? A rhombus is a parallelogram with four congruent sides. Notice that a rhombus does not ALWAYS have right angles like a square, but it does always have congruent sides. A trapezoid is a parallelogram with one pair of opposite sides parallel. Here is an example of a trapezoid.
Similarly, does a rectangle have all sides congruent?
A rectangle is a quadrilateral because it has four sides, and it is a parallelogram because it has two pairs of parallel, congruent sides. All four angles are right angles. All four of its sides are congruent. The third special parallelogram is called a rhombus.
Which shape always has 4 congruent sides?
rhombus
Related Question Answers
What do you call a rectangle with uneven sides?
A quadrilateral is a square if and only if it is both a rhombus and a rectangle (four equal sides and four equal angles). Oblong: a term sometimes used to denote a rectangle that has unequal adjacent sides (i.e. a rectangle that is not a square). Kite: two pairs of adjacent sides are of equal length.Does a rectangle have four right angles?
A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.Does a rectangle diagonal bisect its angles?
The diagonals of a rectangle will only bisect the angles if the sides that meet at the angle are equal: in other words, only if the rectangle is a square. Hence the rectangle must be square. Each diagonal splits the rectangle into two right-angled triangles.How many obtuse angles does a rectangle have?
2 obtuse anglesWhat are the attributes of a rectangle?
The rectangle has the following properties:- All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other).
- All angles are right angles by definition.
- The diagonals are congruent.
What shape does not have right angles?
Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles. Kites have two pairs of adjacent sides that are equal. We can use a Venn diagram to help us group the types of quadrilaterals.Are Consecutive angles supplementary in a rectangle?
A rectangle is a parallelogram, so its opposite angles are congruent and its consecutive angles are supplementary.Can a rectangle have equal sides?
A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides. A square has two pairs of parallel sides, four right angles, and all four sides are equal.Does a square have congruent sides?
A square is one of the most basic geometric shapes. It is a special case of a parallelogram that has four congruent sides and four right angles. A square is also a rectangle because it has two sets of parallel sides and four right angles. All four sides of a rhombus are congruent.What makes a rectangle congruent?
Congruence. If two figures have the same shape and the same size, then they are said to be congruent figures. For example, rectangle ABCD and rectangle PQRS are congruent rectangles as they have the same shape and the same size. Side AB and side PQ are in the same relative position in each of the figures.Is a rectangle a rhombus yes or no?
All four sides of a rhombus are equal. A rectangle is therefore not a rhombus, If it is to be a rhombus, additional properties have to be present. The only time this would happen is if the shape was a square.Is a line a rectangle?
A line is not a rectangle, A representation of a line can be a rectangle, or a series of spheres, or a collection of vibrating objects. A rectangle is made up of 4 segments which each share a common endpoint with two different segments comprising right angles. See, no lines!How do you find the sides of a rectangle?
Explanation: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.Do rectangles have 4 sides?
A rectangle is a four-sided shape where every angle is a right angle (90°). Also opposite sides are parallel and of equal length.What shape has 2 pairs of congruent sides?
| Name of Quadrilateral | Description |

What are congruent sides?
Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.How can you classify a rhombus with four congruent angles?
A rhombus is a parallelogram with four congruent sides. Notice that a rhombus does not ALWAYS have right angles like a square, but it does always have congruent sides. A trapezoid is a parallelogram with one pair of opposite sides parallel.What is a four sided shape with unequal sides called?
A quadrilateral is a square if and only if it is both a rhombus and a rectangle (four equal sides and four equal angles). Oblong: a term sometimes used to denote a rectangle that has unequal adjacent sides (i.e. a rectangle that is not a square).How many congruent angles does a trapezoid have?
A trapezoid is a quadrilateral with two parallel sides. It does not have any requirement as to the size of the angles. In an isosceles trapezoid two pairs of angles are congruent, they are the base angles.Does a rectangle have obtuse angles?
A rectangle is a parallelogram with four right angles. This means that a rectangle has opposite sides parallel and congruent and it also has four right angles. A square is a rectangle with four congruent sides and four right angles. Notice that this trapezoid has two acute angles and two obtuse angles.What shapes have all sides congruent?

| Square | 4 congruent sides. 4 right angles (90°). Opposite sides are parallel. All angles are congruent. |
| Trapezoid | Only one pair of opposite sides is parallel. |
Can a kite have exactly two right angles?
Thus the right kite is a convex quadrilateral and has two opposite right angles. If there are exactly two right angles, each must be between sides of different lengths. All right kites are bicentric quadrilaterals (quadrilaterals with both a circumcircle and an incircle), since all kites have an incircle.What is a 6 sided shape called?
A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… There are names for many different types of polygons, and usually the number of sides is more important than the name of the shape. A regular polygon has equal length sides with equal angles between each side.How many congruent angles does a square have?
fourWhat shapes have both pairs of opposite angles are congruent?
A quadrilateral is a parallelogram if: Both pairs of opposite sides are congruent. If they are congruent, they must also be parallel.What does congruent mean?
If two figures have the same size and shape, then they are congruent. The term congruent is often used to describe figures like this.What are the 7 types of quadrilaterals?
