Question

Sumit constructed an angle of ${90}^o$ and trisected it. Measure of two angles taken together will be

• A. ${20}^o$
• B. ${40}^o$
• C. ${60}^o$
• D. None of these

Answer 1

Answer: (C)

${60}^o$

Trisecting an angle means dividing it in three equal parts.

So if we trisect ${90}^{\circ }$, we get $3$ equal angles ${30}^{\circ }$ each.

On taking two angles together : ${30}^{\circ }$+${30}^{\circ }$ = ${60}^{\circ }$
