**To construct:** Δ ABC in which AB = 2.5 cm, BC = 6 cm and AC = 6.5 cm.

**Steps of construction:**

(a) Draw a line segment BC = 6 cm.

(b) Taking B as centre and radius 2.5 cm, draw an arc.

(c) Similarly, taking C as centre and radius 6.5 cm, draw another arc which intersects first arc at point A.

(d) Join AB and AC.

(e) Measure angle B with the help of protractor.

It is the required Δ ABC where ∠ B = 80**°**.
