Question

construct a triangle pqr with its perimeter =11cm and base angles of 90 degree and 30 degree

Answer 1

Steps of construction
1. Draw a line segment AB = 11 cm
2. At A draw angle 30° and at B draw angle 90°
3. Draw angular bisectors of both angles which intersect each other at X
4.Draw perpendicular bisectors of AX and BX which intersect AB at Y and at Z respectively .
5.Join XY and YZ
Triangle XYZ is required triangle

Answer 2

Solution:

Draw a line of 11 cm.

construct angle of 90° on one side

construct another angle of 30° on other side
