Question

Construct a triangle XYZ in which YZ=5 CM. XZ-XY=2.5 CM. angleY= 75°

Answer 1

Steps of Construction:

(1) Draw YZ = 5 cm

2) Construct angle ZYW = 75° ,with the help of protector or compass.

3) Along YW,set off YT = 3 cm

4) join ZT.

5) Draw a right bisector of ZT ,meeting YT produced at X.

6) Join ZX.

Then ∆ XYZ is the required triangle.
