Question

select all the statements that are true about rectangles.
a. diagonals are congruent.

b. opposite sides are congruent.

c. opposite angles are complementary.

d. opposite sides are parallel.

e. diagonals bisect each angle.

Explanation:

• A: In rectangles, diagonals have equal length (congruent), a defining property.
• B: Rectangles are parallelograms, so opposite sides are congruent.
• C: Opposite angles in rectangles are right angles (90°), so they are supplementary (180°), not complementary (90° total).
• D: Rectangles are a type of parallelogram, so opposite sides are parallel.
• E: Rectangles' diagonals do not bisect angles (this is true for rhombuses/squares, not all rectangles).

Answer:

A. Diagonals are congruent.
B. Opposite sides are congruent.
D. Opposite sides are parallel.
