Question

Each division covers $\frac{45}{360}$ parts of a circle. Which of the following figures describes the angle formed by two such divisions?

• A. 3
• B. 1
• C. 2
• D. None of the given figures describe the angle.

Answer 1

The correct option is B 1

Each division covers
$\frac{45}{360}$ parts of a circle.
Angle made by an entire circle $={360}^0$
Angle subtended by each division on the circle $={45}^0$
Angle made by two such divisions $=45\times 2={90}^0$Therefore, figure 1 describes the angle formed by 2 such divisions.
