Question

Identify all the quadrilaterals that have four right angles.

Answer 1

Define quadrilaterals having four right angles:

1. There are two quadrilaterals whose all four angles are right angles, namely rectangle, square and rhombus.
2. A rectangle is a quadrilateral having all four angles of $90°$ and the opposite sides of equal lengths.
3. A square is a quadrilateral having all four angles of $90°$ and all four sides of equal lengths.

Hence, the rectangles and the squares are the quadrilaterals that have four right angles.
