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.
