Q2 of 49 Page 61

In a triangle ABC, we have AB = 4cm, BC = 5.6cm and CA = 7.6cm. Write the angles of the triangle in ascending order of measures.

The side opposite to the smallest angle is the smallest side and the angle opposite to the largest angle is the largest side


The largest side among the three sides of Δ ABC is CA = 7.6 cm


So the largest angle of Δ ABC is ∠B


The smallest side among the three sides of Δ ABC is AB = 4 cm


So the smallest angle of Δ ABC is ∠C


So in ascending order, the angles will be


∠C< ∠A < ∠B
