## How to Draw Triangles using Geometrical Instruments? - Part 3

#### 1. Draw a triangle DEF with ∠DEF = 130°, ∠DFE = 20° and EF = 6 cm.

**Step 1:**Draw a straight line EF 6 cm long.

**Step 2:**Using a protractor draw an angle of 130° from Point E.

**Step 3:**Using a protractor draw an angle of 20° from Point F.

**Step 4:**Mark the point where the two lines meet as Point D.

Δ DEF is the required triangle.
