**Grade Level**: Year/Grade 8 (age of students is 12-13)

**Length of Lesson**: 30 minutes

## Objectives:

- Students will be able to define the Pythagoras Theorem.
- Students will be able to identify the three sides of the right-angle triangle.
- Students will solve simple problems using Pythagoras Theorem.
- Students will understand the application of Pythagoras Theorem in real-life scenarios.

## Materials Needed:

- Whiteboard/Blackboard
- Chalk/Markers
- Hand-outs with triangles
- Worksheets

## Introduction (5 minutes)

- Ask students if they can identify what a right-angle triangle is.
- Draw a simple right-angle triangle on the board and explain that it has three sides - base, height, and hypotenuse.
- Explain that today's lesson is about the Pythagoras Theorem and how it can be applied to find the length of the hypotenuse.

## Body (20 minutes)

### Defining the Pythagoras Theorem (5 minutes)

- Write the formula for the Pythagoras Theorem on the board:
`a² + b² = c²`

.
- Explain that
`a`

and `b`

represent the base and height, while `c`

represents the hypotenuse.
- Emphasize that this formula only applies to right-angle triangles.

### Identifying the Three Sides of a Right-Angle Triangle (5 minutes)

- Hand out worksheets to students with simple right-angle triangles.
- Ask students to identify the base, height, and hypotenuse of the triangle.

### Solving Problems using Pythagoras Theorem (10 minutes)

- Provide examples of right-angle triangles on the board.
- Ask students to calculate the length of the hypotenuse using the Pythagoras Theorem.
- Guide students through the steps to calculate the length of the hypotenuse.

### Application of Pythagoras Theorem (5 minutes)

- Give real-life scenarios where Pythagoras Theorem can be applied.
- Ask students to identify real scenarios where Pythagoras Theorem can be applied.

## Conclusion (5 minutes)

- Review the Pythagoras Theorem and its application to real-life scenarios.
- Hand out homework as necessary.
- Answer any questions students may have.
