The diagonals of a rectangle are inclined to one side of the rectangle at 25°. The acute angle formed between the diagonals is:
A25°
B55°
C50°
D40°
Answer & Solution
Correct answer: C. 50°
1. Each diagonal makes 25° with the side, and the diagonals bisect each other.
2. The triangle formed at the intersection with that side is isosceles, with two base angles of 25°.
3. The acute angle between the diagonals is an exterior angle equal to 25° + 25° = 50°.
