## Drawing Triangles using Geometrical Instruments - Part 3

*Example:*

*Example:*

*Draw a right-angled triangle XYZ with ∠XYZ = 90°, YZ = 5 cm and XY = 4 cm.*

Step 1:Draw a straight line YZ 5cm long.

Step 2:Using a protractor draw a right angle (an angle of 90°) from Point Y.

Step 3:Mark the point X so that XY = 4 cm.

Join Point X to Point Z.

Δ is the required right-angled triangle.

*Example 4*

*Example 4*

*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.

ΔDEF is the required triangle.
