Every triangle has three angles that total 180o. In an equilateral triangle, there are three 60o angles.
All triangles have internal angles summing to 180 degrees. An equilateral triangle has three equal angles, each of which is 180/3 = 60 degrees.
The sums of their interior angles both total to 360 degrees.
because its a right triangle For a triangle to be equilateral, all angles and sides must be of a same length. Since the total of the angles of a triangle can only be up to 180, it is impossible for there to be three 90 degree angles, which equal to 270 degrees..
All triangles have a total of 180 degrees for interior angles in Euclidean plane geometry
Each of the three angles is 60 degrees, resulting in a total of 180.
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).
Because the total sum of angles in any triangle adds up to 180 degrees.
- 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.
There are a total of 3 lines of symmetry in an equilateral triangle
no. A triangle has total 180 degrees. An equilateral triangle requires all three angle measures to be the same, so every angle HAS to be equal to 60 degrees. A right triangle has 1 90 degree angle and 2 45 degree angles, so it can never be an equilateral triangle.
