Area of Equilateral Triangle - Formula, Derivation, Examples
WebExample 1: If each vertex angle of a triangle measures 60°, identify the type of triangle based on triangle properties. Solution: It is given that all the interior angles of the given triangle measure 60° each. We know that all the angles in an equilateral triangle measure the same and they sum up to 180°, hence, each angle measures 60°. WebAn equilateral triangle is a regular polygon with n = 3 sides, interior angles of 60 degrees, and exterior angles of 120 degrees. For an equilateral triangle, we have a regular polygon with 3 sides (n = 3). The measure of each interior angle is 180 / 3 = 60 degrees. The measure of each exterior angle is 360 / 3 = 120 degrees. bipp in texas

Show that the angles of an equilateral Triangle are 60∘ each. … WebA triangle's three angles measure up to 180. Since it is a equilateral triangle Sal is constructing, each angle is 60 degrees. Many people become confused when Sal says 120 degrees is one third of the triangle, but he is talking about the arc of the circle. To find the arc or the angle formed by the arc, use this equation: arcX = 2 angleX. dallas business journal bred award
