FREE} All About Angles Worksheets: Classify & Measure Angles ... - Free Printable

The task in the image involves naming different types of angles based on their measurements. The worksheet provides several angles with their measurements and asks students to cut and paste the correct labels for each angle type. Here's how to solve the problem step by step:

Step 1: Understand the Angle Types

Before solving, let’s review the definitions of the different types of angles:
1. Acute Angle: An angle that measures less than 90°.
2. Right Angle: An angle that measures exactly 90°.
3. Obtuse Angle: An angle that measures more than 90° but less than 180°.
4. Straight Angle: An angle that measures exactly 180°.
5. Reflex Angle: An angle that measures more than 180° but less than 360°.

Step 2: Analyze Each Angle

Now, let’s examine each angle provided in the worksheet and determine its type based on its measurement.

#### Angle 1: 90°
- Measurement: 90°
- Type: This is a Right Angle because it measures exactly 90°.
- Label: "Right Angle" (already correctly placed in the worksheet).

#### Angle 2: 120°
- Measurement: 120°
- Type: This is an Obtuse Angle because it measures more than 90° but less than 180°.
- Label: "Obtuse Angle" (already correctly placed in the worksheet).

#### Angle 3: 180°
- Measurement: 180°
- Type: This is a Straight Angle because it measures exactly 180°.
- Label: "Straight Angle" (not yet placed; needs to be cut and pasted).

#### Angle 4: 270°
- Measurement: 270°
- Type: This is a Reflex Angle because it measures more than 180° but less than 360°.
- Label: "Reflex Angle" (not yet placed; needs to be cut and pasted).

#### Angle 5: 45°
- Measurement: 45°
- Type: This is an Acute Angle because it measures less than 90°.
- Label: "Acute Angle" (not yet placed; needs to be cut and pasted).

Step 3: Place the Labels

Using the scissors and glue stick, cut out the labels from the dashed lines at the top of the worksheet and paste them next to the corresponding angles:
1. For the 180° angle, paste the label "Straight Angle".
2. For the 270° angle, paste the label "Reflex Angle".
3. For the 45° angle, paste the label "Acute Angle".

Final Answer

After placing all the labels, the completed worksheet should look like this:
1. 90°: Right Angle
2. 120°: Obtuse Angle
3. 180°: Straight Angle
4. 270°: Reflex Angle
5. 45°: Acute Angle

Thus, the solution is:

\boxed{\text{Straight Angle, Reflex Angle, Acute Angle}}
