Question

# Measure the following angle using a protractor.

- 118°
- 119°
- 117°
- 116°

Hint:

### Note the moving line degree read in the protractor.

## The correct answer is: 118°

### * An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

* The symbol ∠ represents an angle. Angles are measured in degrees (°) using a protractor.

>>>Given that:

>>>From figure, the protractor reads from 0 degrees to exactly 118 degrees.

>>>Angle measured by protractor becomes 118 degrees.

Step 1:

We line up one ray with 0°. We then read the angle measurement where the other ray crosses the protractor.

Step 2:

Reading from the protractor, the given angle measures 118°.

>>>Therefore, the angle measured is exactly 118 degrees.
