Find The Measure Of Each Interior Angle Of An Equilateral Triangle

Find The Measure Of Each Interior Angle Of An Equilateral Triangle. Find the Measure of an Interior Angle of a Triangle - YouTube. Constructing an altitude from any base divides the equilateral triangle into two right triangles each one of which has a hypotenuse equal to the original equilateral triangles side and a leg ½ that length.

In the familiar Euclidean geometry an equilateral triangle is also equiangular. Like an equilateral triangle a square a rectangle a regular hexagon etc the measure of an exterior angle equals. For a polygon where all the angles have the same measure.

Since the interior angles add up to 180 every angle must be less than 180. That is all three internal angles are also congruent to each other and are each 60. Ex72 8 Show that the angles of an equilateral triangle are 60 each. An interior angle is an angle inside the shape.
