In an equilateral triangle, all three angles are equal to 60˚. To find the missing angles in an equilateral triangle, divide the sum of interior angles in a triangle by 3.

The reason the shape changes from 3D to 2D when you get to six triangles has to do with the number of degrees in an equilateral triangle. There are 60 degrees at each vertex of the triangle, so ...

Discusses the properties and types of triangles, explaining that a triangle is a closed figure with three sides and angles. It categorizes triangles into equilateral, isosceles, scalene, obtuse ...

Equilateral triangle. An equilateral triangle is a triangle where all sides are equal and where all angles are equal. Since we know that the angle sum of a triangle is 180 degrees, ...

Equilateral Triangle Symbolism An equilateral triangle, as we’ve already learned, is a "perfect" triangle with 90-degree angles on each corner. All sides are exactly the same length.
