All up a triangle has 180 degrees on the interior so if we add 45 and 38 together we get 83. 180 minus 83 equals 97. So the degrees of the last angle is 97 degrees.
You learn this is seventh grade math.
If each of the 3 interior angles measure 60 degrees then it is an equilateral triangle.
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees

The three interior angles of any triangle add up to 180 degrees
The 3 interior angles of a triangle add up to 180 degrees.
100 degree, 40 degree and 40 degree.
45 degree
60º
45°, 45°, and 90°
If each of the 3 interior angles measure 60 degrees then it is an equilateral triangle.
80 degrees(We're talking strictly about interior angles here.)
No because the 3 interior angles of any triangle always add up to 180 degrees.
A triangle with a 90o interior angle is called a 'right' triangle. BTW, any triangle can have only one 90o interior angle
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
obtuse

The interior angles of a triangle add up to 180. So a triangle with 3 equal sides (or angles) will have 60-degree angles. * * * * * True, but the question is about an isosceles triangle, not an equilateral triangle. The angles of an isosceles triangle are x, x and 180-2x degree where x is a measure between 0 and 90 degrees.
