Question

Identify all the quadrilaterals that have four right angles.

Accepted Answer

Quadrilateral is a two-dimensional closed figure which has four straight sides, four vertices and four angles. Quadrilaterals can be of different types such as rectangle, square, rhombus, parallelogram, trapezium and kite. Each type of quadrilateral has its own properties.

A rectangle is a quadrilateral that has four right angles, opposite equal sides and two sets of parallel opposite sides.

A square is a quadrilateral that has all equal sides and all angles equal to $90 °$

A rhombus is a quadrilateral which has equal sides, opposite parallel sides and opposite equal angles.

A parallelogram is a quadrilateral that has parallel and equal opposite sides and equal opposite angles.

A trapezium is a quadrilateral with at least one pair of parallel sides.

A kite is a type of quadrilateral that has two pairs of equal length sides that join up and its diagonals meet at right angles.

Hence, from the above definitions, we can conclude that square and rectangle are the quadrilaterals that have four right angles.
