In a triangle, the angle a is 56, the angle b is 78 which of the sides of the triangle is the smallest?

In a triangle, opposite large angles also lie large sides and vice versa.

Let’s find the angle C to determine which of the angles is the smallest.

The sum of the angles in the triangle is 180 °, angle A = 56 °, angle B 78 ° by condition.

A + B + C = 180 °.

C = 180 ° – (A + B);

C = 180 ° – (56 ° – 78 °);

C = 180 ° – 134 °;

C = 46 °;

46 ° <56 ° <78 °;

Angle C is the smallest, which means that the smallest side of the triangle lies opposite it.

Side AB is the smallest side of the triangle.
