AB = 4 cm, BC = 7 cm, CA = 3 cm.
Step – 1:
Draw a rough sketch of the triangle and label it with the given measurements.
Step – 2:
Draw a line segment AB of length 4 cm.
Step – 3:
With A as centre, draw an arc of radius 3 cm.
Step – 4:
With B as centre, draw another arc of radius 7 cm such that it intersects first arc at C.
Step – 5:
Join C, A and C, B. The required ∆ABC is constructed. This triangle Is an obtuse angled triangle.
