4. Right Angles (part 1)

4.1. Right Angle : an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.

5. 2) Obtuse Angles

5.1. Obtuse Angle : a form of angle that measures wider than 90° and less than 180°.

6. 3) Acute Angles

6.1. Acute Angles : the small angle which is less than 90°.

7. Rays

7.1. Rays : a part of a line that has one endpoint and extends in one direction without ending.

8. Lines

8.1. Line : a straight set of points that extend in opposite directions without ending.

9. Line-segment

9.1. Line-segment : a part of a line between two endpoints.

10. Perpendicular Lines

10.1. Perpendicular Lines : Lines that meet or cross each other to form right angles

11. Parallel Lines

11.1. Parallel Lines : always the same distance apart. They do not meet.

12. Line of Symmetry
