If we bisect an angle of a rectangle, we get 2 angles each of ______

Options

A. `45 ^(@)`
B. `30^(@)`
C. `60^(@)`
D. `15^(@)`

Answer

To solve the problem of what angles we get when we bisect an angle of a rectangle, follow these steps:

### Step-by-Step Solution:

1. **Understand the Angles in a Rectangle**: A rectangle has four right angles, each measuring 90 degrees.

2. **Identify the Angle to Bisect**: Choose one of the angles of the rectangle to bisect. For example, we can bisect the angle at vertex A.

3. **Bisect the Angle**: To bisect the angle, we draw a line from the vertex (point A) that divides the angle into two equal parts. This means we will create two angles from the original 90-degree angle.

4. **Calculate the Bisected Angles**: Since we are bisecting a 90-degree angle, we divide it by 2:
\[ \text{Bisected Angle} = \frac{90 \text{ degrees}}{2} = 45 \text{ degrees} \]

5. **Conclusion**: Therefore, when we bisect an angle of a rectangle, we get two angles, each measuring 45 degrees.

### Final Answer:
If we bisect an angle of a rectangle, we get 2 angles each of **45 degrees**.
