3. Right Angles (part 1)
3.1. Right Angle : an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
4. Rays
4.1. Rays : a part of a line that has one endpoint and extends in one direction without ending.
5. Lines
5.1. Line : a straight set of points that extend in opposite directions without ending.
6. Line-segment
6.1. Line-segment : a part of a line between two endpoints.
7. Perpendicular Lines
7.1. Perpendicular Lines : Lines that meet or cross each other to form right angles
8. Parallel Lines
8.1. Parallel Lines : always the same distance apart. They do not meet.

13. 2) Obtuse Angles
13.1. Obtuse Angle : a form of angle that measures wider than 90° and less than 180°.
14. 3) Acute Angles
14.1. Acute Angles : the small angle which is less than 90°.
15. Line of Symmetry
15.1. Line of Symmetry : is the imaginary line where you could fold the image and have both halves match exactly.
