Find the exterior angles in each of the following triangles :

Answer»

a) From the figure

∠A = 60°, ∠B = 73°

Exterior angle of a triangle is equal to the sum of its opposite interior angles.

Exterior angle at C = ∠A + ∠B

= 600 + 730

= 133°

b) From the figure,

∠D = 90°, ∠E = 30°

Exterior angle of a triangle is equal to the sum of its opposite interior angles.

Exterior angle at

F = ∠D + ∠E

= 90° +.30°

= 120°
