Question

For what value of BC + AC , the construction of a triangle ABC is possible , if AB =7cm and angle A is 45 degree​

Answer 1

Step-by-step explanation:

Given, AB = 7cm, BC + CA = 9 cm and angle A = 45 degree

Steps of Construction:

1. Draw AB = 7 cm

2. Construct ∠BAP = 45 degree

3. From ray AP cut off line segment AD = BC + CA = 9 cm

4. Join B and D

5. Construct the perpendicular bisector of BD meeting AD at C i.e. draw arcs on both sides

of BD with the help of compass taking B and D as centers.

6. Join B and C.

Now, we get the required triangle ABC as shown in the figure.
