Question
Construct a triangle ABC in which BC = 7 cm, ∠B = 75° and AB + AC = 13 cm.
Solution
The below given steps will be followed to construct the required triangle.
Step I:- Draw a line segment BC of 7 cm. At point B, draw an angle of 75°, say ∠XBC.
Step II:- Cut a line segment BD = 13 cm (that is equal to AB + AC) from the ray BX.
Step III:- Join DC and make an angle DCY equal to ∠BDC.
Step IV:- Let CY intersect BX at A. ΔABC is the required triangle.
