Find The Measure Of Each Interior Angle Of An Equilateral Triangle. Equilateral triangles have sides of equal length with angles of 60. As sum of the interior angles 180o.
Properties of Interior Angles The sum of the three interior angles in a triangle is always 180. Hope that it will be useful to you. From the above diagram we can say that the triangle has three interior angles.
Therefore angle A angle B angle C tagEq2.
Now the side of the original equilateral triangle lets call it a is the hypotenuse of the 30-60-90 triangle. 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. This equilateral triangle calculator calculates any equilateral triangle by entering one of its properties except angles because α β γ 60. And each interior angle of equilateral triangle is 60.
