Question

In the following figure, if point A is shifted to point B along the ray PX such that PB = 2PA, then the measure of ∠BPY is ______.

Options

• greater than 45°

• 45°

• less than 45°

• 90°

Answer 1

In the following figure, if point A is shifted to point B along the ray PX such that PB = 2PA, then the measure of ∠BPY is 45°.

Explanation:

Since, the increase and decrease in the length of arms of an angle does not affect the angle made by them.

∴ ∠BPY = 45°
