### Process (How to do the activity)

- To construct a right triangle what parameters are required.
- How many angles and sides need to be known. How many right angles can be in a triangle?
- What is side opposite to right triangle called? Is this parameter required to construct a right angled triangle?
- Can a right triangle be constructed knowing two adjacent sides of a right triangle that are the arms of the right angle.

**Evaluation at the end of the activity**

- What is the minimum value of the hypotenuse required to make the triangle
