QN0029349

A trapezium has one pair of opposite sides parallel. If one angle is 115°, the adjacent angle on the same side is

(A) 65°
(B) 75°
(C) 115°
(D) 245°

QN0029350

A kite has two pairs of adjacent equal sides. Which diagonal always bisects the other at right angles?

(A) Both diagonals bisect each other
(B) The diagonal joining unequal angles
(C) The diagonal joining the vertices where equal sides meet
(D) Neither diagonal

Correct Answer: C

Explanation:

In a kite, the diagonal joining the vertices where equal sides meet bisects the other diagonal at 90°.

QN0029352

A quadrilateral has angles in the ratio 2 : 3 : 4 : 9. The largest angle is

(A) 90°
(B) 120°
(C) 150°
(D) 180°

Correct Answer: D

Explanation:
