## 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.
