each angle is equal to 45°

ileach angle is equal to 60°

wo of the angles are acute

il two of the angles are right angles

iv. two of the angles are obtuse

Fig. 13 no

1. The angles of a triangle are arranged in ascending order of magnitude. If the

difference between two consecutive angles is 10", find the three angles.

IHints

: Let the three angles arranged in ascending order be x”, (x + 10) and

(x+20)". Then, + x + 10 + x + 20 = 180)

2. If one angle of a triangle is equal to the sum of the other two, show that the

triangle is right angled triangle
