Solution

This statement is False.

Explanation:

If one angle of a triangle is kept fixed, then the measure of the remaining two angles can’t vary inversely with each other.

E.g. In ΔABC, ∠A + ∠B + ∠C = 180°  ...[∵ Sum of all angles of a triangle is 180°]

If ∠A = 50°, then ∠B + ∠C = 180° – 50° = 130°

So, it is not depending on any proportion by applying angle sum properties of a triangle.
