- 10. . An angle less than 90 degrees. Acute Angle
- 11. Obtuse Angle An angle greater than 90 degrees
- 12. Right Angle An angle that is 90 degrees.
- 13. Straight Angle A straight angle is just like a straight line and always equals 180 degrees.
- 14. Vertex/Vertices The vertex is where both lines meet to make an angle. Vertices are vertex plural.
- 15. Complementary Complementary is when you have two angles and when added equal 90 degrees 45 45
- 16. Supplementary When two angles equal 180 degrees 70 110
- 17. Vertical/opposite An angle on top of the other a B
- 18. Adjacent Two angles that share a line B B
