If one angle of a triangle is kept fixed then the measure of the remaining two angles vary inversely with each other.

False

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 Δ]

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.
