b
c
d
e
a. a
b. b
c. c
d. d
e. e

Explanation:

• Figure A: It is a right triangle, so it has a right angle (90°), meaning two sides are perpendicular.
• Figure B: It is an obtuse triangle with no right angles, so no perpendicular sides.
• Figure C: It is a parallelogram (specifically a rhombus or slanted parallelogram), with no right angles, so no perpendicular sides.
• Figure D: It is a trapezoid, but the sides are not perpendicular (it's a non - right trapezoid in appearance).
• Figure E: The vertical and horizontal sides (the top and the left/right vertical parts) appear to form right angles, so there are perpendicular sides.

Answer:

A. A
E. E
