Equilateral Triangle Degrees Math
The sides of an equilateral triangle are congruent.
Equilateral triangle degrees math. Recall from above that an equilateral triangle is also an isosceles triangle. The equilateral triangle is the only acute triangle that is similar to its orthic triangle with vertices at the feet of the altitudes the heptagonal triangle being the only obtuse one. To go one step even further since we are dealing with an equilateral triangle the interior angles are equally divided into 60 degrees each. The reason for this lies in the following fact.
An equilateral triangle is also called an equiangular triangle since its three angles are equal to 60. Since the sum of a triangle s angles is always 180 degrees each angle in an equilateral triangle must measure 60 degrees. Since de ef the base angles d and f are congruent. See full answer below.
The sum of the angles of any triangle. Since we are dealing with a triangle here we know that the angles inside it must add up to 180 degrees. Having same length sides and 60 degree interior angles are the hallmarks of a good equilateral. We can find the shape of a triangle in a rack in billiards a road side sign board and a slice of pizza around us.
This is because we must divide 180 degrees evenly between the three. In geometry an equilateral triangle is a triangle whose all three sides are of equal length.
