In this video, I explain what angles are and what they are used for. I teach how to recognize and name angles based on their size and the position of their sides. I present how to use a set square to distinguish between acute, right, obtuse, straight, reflex, and full angles. I show how to label the sides, vertex, and interior of an angle, explain the differences between each type of angle using visual examples, and demonstrate how to draw each of these angles using a set square and arcs that indicate the angle’s measure. Contents: 1. What angles are used for 2. What an angle is: sides, vertex, and interior 3. Acute angle – definition and checking with a set square 4. Right angle – definition and marking 5. Obtuse angle – definition and checking 6. Straight angle – definition 7. Reflex angle – definition 8. Full angle – definition 9. Summary of types of angles 10. How to draw an acute angle 11. How to draw a right angle 12. How to draw an obtuse angle 13. How to draw a straight angle 14. How to draw a reflex angle 15.
