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.
