Answer to Problem 2CT

Constructed a triangle with ${30}^0,{60}^0,{90}^0$ with length y .

Explanation of Solution

Given:

Given angles are ${30}^0,{60}^0,{90}^0$ and assume $y=20\text{mm}$ .

Construction:

1. with 20 mm height a vertical line is drawn.

2. with protracter ${60}^{\circ }$ is marked and extended that line up to horizontal axis.

3. AB is joined to get a triangle of angles ${30}^0,{60}^0,{90}^0$ .
