Question

Construct a triangle ABC whose perimeter is 12m. and base angles are 50° and 70°.​

Answer 1

Answer:

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

2. Make ∠ LPQ= 50° and ∠ MQP = 70°

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.

Answer 2

Answer:

YOUR QUESTION :

Construct a triangle ABC whose perimeter is 12m. and base angles are 50° and 70°.

SOLUTION :

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.
