In Fig. 5.12, lines l and m intersect each other at a point. Which of the following is false?

l and m intersect at a point

∠a = ∠b (Vertically Opposite)

∠d = ∠c (Vertically Opposite)

∠a + ∠d = 180° (Forms a linear pair)

Hence Option A, B & C are correct

∠a ≠ ∠d

In Fig. 5.10, the value of x is

In Fig. 5.11, if AB || CD, ∠APQ = 50° and ∠PRD = 130°, then ∠QPR is

If angle P and angle Q are supplementary and the measure of angle P is 60°, then the measure of angle Q is

In Fig. 5.13, POR is a line. The value of a is
