## Drawing Triangles using Geometrical Instruments - Part 1

#### 1. Draw an equilateral triangle with side 5 cm.

**Step 1:**Draw a straight line 5 cm long. Call it AB.

**Step 2:**Using a protractor draw an angle of 60° from Point A.

Each angle of an equilateral triangle is 60°.

**Step 3:**Using a protractor draw an angle of 60° from Point B.

**Step 4:**Mark the point where both these lines meet as C.

**CHECK**

- Measure the lengths of lines AC and BC.
- They should each be equal to 5 cm.
- Using a protractor measure ∠ACB.
- It should be equal to 60°.
- Δ ABC is the required equilateral triangle.

Each side of an equilateral triangle is of the same length.
