Measuring Angles using a protractor interactive worksheet | Live ... - Free Printable

To solve the problem of matching the angles shown in the protractors to their corresponding degree measures, we need to carefully read each protractor and determine the angle it is measuring. Here's a step-by-step explanation:

---

Step 1: Understand how to read a protractor

- Protractors have two scales: one starting from 0° on the left and increasing clockwise, and the other starting from 0° on the right and increasing counterclockwise.
- The angle is measured by aligning one side of the angle with the baseline (the straight line at the bottom of the protractor) and reading the degree where the other side of the angle intersects the scale.

Step 2: Analyze each protractor

#### Protractor 1:
- The baseline is aligned with the 0° mark on the left.
- The other side of the angle points to 45° on the scale.
- Angle = 45°

#### Protractor 2:
- The baseline is aligned with the 0° mark on the left.
- The other side of the angle points to 36° on the scale.
- Angle = 36°

#### Protractor 3:
- The baseline is aligned with the 0° mark on the left.
- The other side of the angle points to 119° on the scale.
- Angle = 119°

#### Protractor 4:
- The baseline is aligned with the 0° mark on the left.
- The other side of the angle points to 70° on the scale.
- Angle = 70°

#### Protractor 5:
- The baseline is aligned with the 0° mark on the left.
- The other side of the angle points to 140° on the scale.
- Angle = 140°

Step 3: Match the angles to the given options

Now, we match the angles we determined to the provided options:

1. Protractor 1: 45°
2. Protractor 2: 36°
3. Protractor 3: 119°
4. Protractor 4: 70°
5. Protractor 5: 140°

Final Answer:

\[
\boxed{
\begin{array}{ll}
1) & 45^\circ \\
2) & 36^\circ \\
3) & 119^\circ \\
4) & 70^\circ \\
5) & 140^\circ \\
\end{array}
}
\]
