Question 34

State whether the given statement is True or False.

If the arms of an angle on the paper are decreased, the angle decreases.

Answer 1

An angle is a measure of an arc between two rays at a common point called vertex.

In the above figure, the measure of $\angle BPY$ is ${45}^{\circ }$.

The measure of the $\angle BPY$ doesn't change with the change in the length of the adjacent sides.

$\therefore$ $\angle BPY$ = $\angle APY$ = ${45}^{\circ }$ .

If the size of the arms changes, then there will be no change in the measure of the angle formed by those arms.

Hence, the given statement that if the arms of an angle on the paper are decreased, the angle decreases is false.
