Question

8. Maximum number of right angles in a right angled triangle are
(a) 2 (b) 1 (c) 3 (d) 0

Answer 1

Maximum number of right angles in a right-angled triangle is (b) 1.

Explanation:

• The sum of the interior angles of a traingle is 180°.

• For a right-angled traingle, one angle is 90° for sure and the sum of the other two angles is (180° - 90°) = 90°.

• Without losing generosity, we take another angle being 90°.

• Then the third angle be (90° - 90°) = 0°, which is contradictory to form a triangle.

• Assumption is wrong and there can be only one right angle in a right-angled traingle.
