3. Points

A point is a precise location in space. It is labeled with a letter.

4. Lines Two pointsconnected going two differentways 5. Planes A flat surface 6. Skew Line not in the same plane 7. Line segment A line pointing both direction 8. Ray A line pointing one way 9. Intersecting Lines Line that intersects 10. Perpendicular Two Lines lines the same plane but will never touch 11. Parallel Two line that will never intersect 12. ANGLES

13. Acute An angle less than 90 degrees 14. Obtuse An angle over 90 degrees 15. Right An angle that is 90 degrees 16. Straight A 180 degree angle 17. Vertex/ verticies A point where two lines meet 18. Complementary Two angles adding to 90 degrees 19. SupplementaryTwo angles adding to 180 degrees 120 60 20. Vertical/ opposite Two angles on opposite sides that equal the same amount of degrees 21. Adjacent Angles that are side by side 22. Triangles

Right

Obtuse

Acute
