Question

Shelly drew a figure on the blackboard. Identify the types of angles made in the figure.

• A. A is acute, and B is obtuse.
• B. B is acute, and A is obtuse.
• C. Both are acute angles.
• D. Both are obtuse angles.

Answer 1

The correct option is A A is acute, and B is obtuse.

Let us observe the given figure.
There are two angles, A and B.

Observe angle A:
The above figure has an angle less than 90${}^{\circ }$. An acute angle is an angle that measure less than 90${}^{\circ }$.

Therefore, the angle made by these lines is acute.

Observe angle B:
The above figure has an angle more than 90${}^{\circ }$ and less than 180${}^{\circ }$. An obtuse angle is an angle that measures more than 90${}^{\circ }$ and less than 180${}^{\circ }$.

Therefore, the angle made by these lines is obtuse.
