What shape is a 4 sided polygon with 4 right angles?
Square
Here are a few common quadrilaterals: Square: A square has four right angles and four sides of equal length; also, both pairs of opposite sides (sides directly across from each other) are parallel. Rectangle: Like a square, a rectangle has four right angles and two pairs of opposite sides that are parallel.
What shape has 4 right angles and all 4 sides are congruent?
square
A square can be defined as a rhombus which is also a rectangle – in other words, a parallelogram with four congruent sides and four right angles.
What is a rectangle with 4 right angles?
A rectangle is a quadrilateral with 4 right angles (90°). In a rectangle, both the pairs of opposite sides are parallel and equal in length. Properties of rectangles: All angles are right angles.
How do you prove that ABCD is a rectangle?
– The diagonals are congruent. Let’s see why we can claim that the diagonals are congruent. Here is a sample proof: Given: Quadrilateral ABCD is a rectangle….Prove it is a Rectangle.

Does a rectangle have 4 sides?
Rectangle: A rectangle is a two-dimensional figure with four sides, four interior right angles, and four corners. The opposites sides of a rectangle are equal. A rectangle has four angles, with each angle measuring 90º. Similar to a square, a rectangle is also referred to as an equiangular quadrilateral.
Do all rectangles have 4 right angles?
Yes, all rectangles have right angles.
Is a rectangle a right angle?
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. Opposite sides of a rectangle are parallel.
What is a shape with 4 right angles?
A rectangle is a special parallelogram that has 4 right angles. Subsequently, one may also ask, what quadrilateral has only 2 right angles? Also, what shape has 2 right angles and no line segments? It could be a trapezoid. Because there are only two right angles, it can’t be a square or a rectangle.
How are the sides of a rectangle defined?
A rectangle is characterized by length (L) and width (W). Both length and width are different in size. In the figure above, a rectangle ABCD has four sides as AB, BC, CD, and DA and right angles A, B, C, and D.
Can a rectangle have 2 right angles and a square?
Because there are only two right angles, it can’t be a square or a rectangle. Because there are no equal length sides, it’s not a parallelogram at all. In this manner, can a trapezoid have 2 right angles? Explanation: A trapezoid can have either 2 right angles, or no right angles at all.
How many right angles does a rhombus have?
A square has two pairs of parallel sides, four right angles, and all four sides are equal. It is also a rectangle and a parallelogram. A rhombus is defined as a parallelogram with four equal sides.
