The diagonals of a shape are perpendicular if they form a right angle.
Let us consider the shapes individually:
1. KITE:
A kite has perpendicular diagonals.
2. SQUARE:
A square has perpendicular diagonals.
3. TRAPEZOID:
A trapezoid does not have perpendicular diagonals.
4. RHOMBUS
A rhombus has perpendicular diagonals.
5. PARALLELOGRAM
A parallelogram does not have perpendicular diagonals.
