Question

What would be the measure of all the angles in a scalene triangle?

(a) 60°, 60° and 60°

(b) 120°, 30° and 30°

(c) 90°, 45° and 45°

(d) 60°, 30° and 90°

The question was posed to me in an interview for job.

My question is from Quadrilaterals topic in chapter Quadrilaterals of Mathematics – Class 8

Answer 1

Right answer is (d) 60°, 30° and 90°

Easy explanation: In a scalene triangle the measure of all the angles and the sides is different. The options other then 60°, 30° and 90° are either equilateral triangles or isosceles triangles.
