Q53 of 106 Page 310

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.

If x and y are in inverse proportion, then (x + 1) and (y + 1) are also in inverse proportion.

If p and q are in inverse variation, then (p + 2) and (q – 2) are also inverse proportion.

When two quantities are related in such a manner that, if one increases, the other also increases, then they always vary directly.

When two quantities are related in such a manner that if one increases and the other decreases, then they always vary inversely.
