# 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.
