Question

Construct a triangle ABC. so that angle B = 60 degree, angle C= 75 degree and also AB+BC+AC= 12.5 cm​

Answer 1

Step-by-step explanation:

1.Steps of Construction :

2.Draw a line segment, say XY equal to BC + CA + AB = 10 cm.

3.Make angle LXY equal to 60o and angle MYX equal to 45o.

4.Bisect LXY and MYX. ...

5.Draw perpendicular bisector PQ of AX and RS of AY.

6.Let PQ intersect XY at B and RS intersect XY at C.

7.Join AB and AC.

8.ABC is the required triangle.
