Question

Two acute angles may form -

• A. Right Angle $\left({90}^o\right)$
• B. Obtuse Angle
• C. Straight Angle $\left({180}^o\right)$
• D. Another Acute Angle

Answer 1

Answer: (A), (B), (D)

Another Acute Angle

We know acute angles are those angles that measure less than ${90}^o$.

Example: ${45}^o$ is an acute angle.
When we add two ${45}^o$ angles, we get a right angle.

Also, ${50}^o$ is an acute angle.
When we add two ${50}^o$ angles, they will form ${100}^o$ angle, which is an obtuse angle.
Obtuse angles are those angles that measure more than ${90}^o$.

Further, ${20}^o$ is an acute angle.
When two ${20}^o$ angles are combined, they form ${40}^o,$ which is an acute angle.

Hence, option $\left(a\right)$, $\left(b\right)$ and $\left(d\right)$ are correct.
