equilateral...
60+A+B=180

ALL ANGKES ARE 60

sanusingh: ok

sky19: it is an equilateral triangle. by exterior angle property the measure of angle formed with the exterior angle is 180-60. hence measure of all angles is same then it is called an equilateral triangle.

sky19: *180-120

sky19: which is equal to 60
