What is an angle?
An angle is formed by two rays that share a common endpoint called a vertex.

#### Slide 4 -Slide

Use visual aids and ask students to identify the vertex, rays, and angle in different examples.
Types of Angles
There are four main types of angles: acute, right, obtuse, and straight.

#### Slide 5 -Slide

Provide examples of each type of angle and ask students to identify and name them.
Acute Angles
Acute angles measure less than 90 degrees and look like a 'sharp' angle.

#### Slide 6 -Slide

Ask students to give examples of acute angles and measure them using protractors.
Right Angles
Right angles measure exactly 90 degrees and look like the corner of a square.

#### Slide 7 -Slide

Provide examples of objects with right angles and ask students to identify and draw them.
Obtuse Angles
Obtuse angles measure between 90 and 180 degrees and look like a 'blunt' angle.

#### Slide 8 -Slide

Ask students to give examples of obtuse angles and measure them using protractors.
Straight Angles
Straight angles measure exactly 180 degrees and look like a straight line.

#### Slide 9 -Slide

Provide examples of objects with straight angles and ask students to identify and draw them.
Practice
Use the following image to identify and name the different types of angles.

#### Slide 10 -Slide

Provide an image with different types of angles and ask students to identify and name them in English.
