Question

10. In triangle interior opposite angle is always less than:
(a) any angle of the triangle
(b) opposite angle
(c) right angle
(d) exterior angle​

Answer 1

Answer

(d) exterior angle

Answer 2

(d) exterior angle​

Angles in a triangle:

• In a triangle, there are three interior angles by which a triangle is formed.
• The sum of the interior angles of a triangle is always 180°.
• However, if we sum all the angles outside the triangle, then it will be always 360°.
• Now, the sum of interior opposite angles in a triangle will always be less than 180°.

Hence, In the triangle, interior opposite angle is always less than the exterior angle.
