Math with Mr. Jay: Types of Angles

Introduction

• This video provides a quick review of five different types of angles.

1. Acute Angle

• An acute angle measures less than 90 degrees.
• Example: Angle measuring 27 degrees.

2. Obtuse Angle

• An obtuse angle is greater than 90 degrees but less than 180 degrees.
• Example: Angle measuring 143 degrees.

3. Straight Angle

• A straight angle measures exactly 180 degrees.
• Example provided for clarity.

4. Reflex Angle

• Reflex angles are greater than 180 degrees but less than 360 degrees.
• A full rotation (360 degrees) creates a full circle.
• Example: Angle measuring 298 degrees.

5. Right Angle

• A right angle is exactly 90 degrees.
• Often indicated by a square in the corner, without explicitly stating "90 degrees".

Conclusion

• Mr. Jay concludes the video by hoping the review helps viewers understand the different types of angles.
• Encourages viewing until next time.
