Question

Construct a triangle whose perimeter is 12 cm and base angle is 45 degree and 60 degree

Answer 1

Step-by-step explanation:

1. Draw a line segment PQ = AB + BC + CA = 12 cm.

2. Make ∠ LPQ= 45° and ∠ MQP = 60°

3. Now bisect ∠ LPQ and ∠ MQP such that their bisectors meet at A.

4. Draw perpendicular bisector of AP and AQ i.e. XY and ST intersecting PQ at B and C respectively.

5. Join AB and AC
