Question

Construct a triangle pqr where PQ is 4.2 cm and angle p is 30 ' and angle r is 45' . Draw a triangle.

Answer 1

Step1 draw line PQ

Step 2 construct 30 degree angle at P

Step 3 since you can't draw angle R find angle q. Angle sum property = 180-75 =105 degree

Step4 construct 105 degree angle at q

Step 5 extend both the arms to form triangle PQR
