An isosceles triangle

Each of the interior angles of an equilateral triangle is 120 degrees.

Angle A + Angle B + Angle C = 180 degrees. 30+90+C=180 120+C=180 C=60 degrees.

30 degrees each

Any triangle that has an angle measuring 90 degrees is a right triangle.

An obtuse angled triangle can have can have one internal angle of 120 degrees.

Yes it can.

60 degrees, 120 degrees

The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.

An isosceles triangle

120 degrees.

180-120-35 = 25 degrees

It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees

a triangle has 180 degrees 35+85=120 180-120=60 the third side is 60 degrees

no because none of the angles are 90 degrees

draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.

120 degrees. Each interior angle of an equilateral triangle is 60 degrees, so each exterior angle is 180 - 60 = 120 degrees It can also be worked out by the formula Exterior angle of a polygon = 360/no. of sides of the polygon = 360/3 = 120Each exterior angle measures 120 degrees and each interior angle measures 60 degrees because there are 180 degrees on a straight line.
