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
12.1. Line of Symmetry : is the imaginary line where you could fold the image and have both halves match exactly.
