Understanding Angles
An angle is formed when two rays (sides) meet at a common endpoint called the vertex. Angles are typically measured in degrees (°) with a full rotation being 360°. Understanding angles involves recognizing various types of angles, which can be categorized as follows:
- Acute Angle: An angle that measures less than 90°.
- Right Angle: An angle that measures exactly 90°.
- Obtuse Angle: An angle that measures more than 90° but less than 180°.
- Straight Angle: An angle that measures exactly 180°.
- Reflex Angle: An angle that measures more than 180° but less than 360°.

5. Answer Key
Including an answer key at the end of the worksheet allows students to check their work and understand any mistakes they made.
Measurement Techniques
Understanding how to measure angles accurately is essential for students. Here are some common techniques:
Using a Protractor
A protractor is a commonly used tool for measuring angles. The steps for using a protractor include:
1. Place the Protractor: Align the center point of the protractor with the vertex of the angle.
2. Align the Base Line: Ensure that one side of the angle lies along the baseline of the protractor.
3. Read the Measurement: Look at the scale on the protractor where the other side of the angle intersects. This gives the angle measurement in degrees.
Using a Compass and Straightedge
For constructing angles, a compass and straightedge can be used. The steps include:
1. Draw a Base Line: Use the straightedge to draw a line segment.
2. Place the Compass Point: Place the compass point on one endpoint of the line segment.
3. Set the Angle: Open the compass to the desired angle measurement and draw an arc that intersects the base line.
4. Connect the Points: Use the straightedge to draw a line from the endpoint to the intersection point, creating the desired angle.
