180 degrees
Yes, actually it has to be. The only type of triangle with even sides is an equilateral triangle, but all of the angles of an equilateral are 60 degrees, because everything is equal and 180(total degrees within a triangle)/3(number of angles)=60(degrees per angle of an equilateral).
Each of the three angles is 60 degrees, resulting in a total of 180.
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
Because the total sum of angles in any triangle adds up to 180 degrees.
Every triangle has three angles that total 180o. In an equilateral triangle, there are three 60o angles.
180 degrees
An equilateral triangle has three equal angles, each measuring 60 degrees. So, there are a total of 180 degrees in an equilateral triangle.
No. The three interior angles of any triangle, no matterwhat shape it is, always total 180 degrees.
The sums of their interior angles both total to 360 degrees.
If all angles in a triangle are equal to 60 degrees, then the triangle is an equilateral triangle. In an equilateral triangle, all three sides are equal in length. This property is a consequence of the triangle angle sum theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. Therefore, if each angle is 60 degrees, the total sum of the angles in the triangle is 180 degrees, satisfying the theorem.

All triangles have a total of 180 degrees for interior angles in Euclidean plane geometry

- Like all triangles, the angles must total to 180 degrees. - Both have the same formula for their areas, although the height of an equilateral triangle must be calculated from the side length. - Both have at least 2 acute angles (all three are 60 degrees in an equilateral triangle) and no obtuse angles. - Both figures have three sides. - Both figures have three angles.
