Measure the Angle Worksheet - Top Teacher - Free Printable

To solve the problem of measuring the angles in the given image using a protractor, follow these steps:

Step 1: Understand the Task

- You need to measure each angle to the nearest degree.
- Use a protractor for measurement.
- If the angle lines are too short, extend them using a ruler.
- After measuring, label each angle as either acute (less than 90°) or obtuse (greater than 90° but less than 180°).

Step 2: Measure Each Angle

#### Angle 1:
- Place the protractor's center on the vertex of the angle.
- Align the protractor's baseline with one side of the angle.
- Read the angle measurement where the other side of the angle intersects the protractor scale.
- The angle appears to be approximately 30°.
- Label it as acute.

#### Angle 2:
- Follow the same procedure as above.
- The angle appears to be approximately 45°.
- Label it as acute.

#### Angle 3:
- Extend the sides of the angle if necessary.
- Measure the angle.
- The angle appears to be approximately 120°.
- Label it as obtuse.

#### Angle 4:
- Extend the sides of the angle if necessary.
- Measure the angle.
- The angle appears to be approximately 135°.
- Label it as obtuse.

#### Angle 5:
- Measure the angle.
- The angle appears to be approximately 60°.
- Label it as acute.

#### Angle 6:
- Extend the sides of the angle if necessary.
- Measure the angle.
- The angle appears to be approximately 100°.
- Label it as obtuse.

Step 3: Record the Measurements and Labels

Here are the measurements and labels for each angle:

1. Angle 1: 30° (Acute)
2. Angle 2: 45° (Acute)
3. Angle 3: 120° (Obtuse)
4. Angle 4: 135° (Obtuse)
5. Angle 5: 60° (Acute)
6. Angle 6: 100° (Obtuse)

Final Answer:

\[
\boxed{
\begin{array}{ll}
\text{Angle 1: } 30^\circ & \text{(Acute)} \\
\text{Angle 2: } 45^\circ & \text{(Acute)} \\
\text{Angle 3: } 120^\circ & \text{(Obtuse)} \\
\text{Angle 4: } 135^\circ & \text{(Obtuse)} \\
\text{Angle 5: } 60^\circ & \text{(Acute)} \\
\text{Angle 6: } 100^\circ & \text{(Obtuse)}
\end{array}
}
