Question

An angle of ${45}^{\circ }$ is drawn using a compass and a ruler. The value of its supplementary angle is ${135}^{\circ }$ . State whether the statement is True or False .

• A. 45°
• B. 205°

Answer 1

The correct option is A

45°

Two angles are supplementary when they add up to ${180}^{\circ }$.

Therefore, the supplementary angle of ${45}^{\circ }$ is,

${180}^{\circ }$ - ${45}^{\circ }$ = ${135}^{\circ }$
Hence , the statement is True .
