An equilateral triangle has three sides of the same length and three angles equal to one another. Enter the number of degrees in each of its angles.

توضیح

The three angles are equal and must share the 180 degrees a triangle holds, so each takes 180 divided by 3. Entering 90 imports the right angle that learners expect to meet everywhere, yet three angles of that size would run to 270 degrees and burst the triangle total.
