It isn't a theorm, it is a formula. The formula states that for a polygon with S sides, the sum of the interior angles is equivilant to (S-2)times 180
The sum of all inner angles within a triangle is 180 degrees.
180 degrees
180 degrees
The 3 inside angles of any triangle add up to 180 degrees.
The sum of the interior angles of a triangle in euclidean geometry equal 180 degrees
The theorem that states every triangle's angles add up to 180 degrees
In a triangle, the sum of the measures of the angles is 180 degrees.
If all angles in a triangle are equal to 60 degrees, then the triangle is an equilateral triangle. In an equilateral triangle, all three sides are equal in length. This property is a consequence of the triangle angle sum theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. Therefore, if each angle is 60 degrees, the total sum of the angles in the triangle is 180 degrees, satisfying the theorem.
The sum of all inner angles within a triangle is 180 degrees.
A triangle's angles always total 180 degrees
The 3 interior angles of an equilateral triangle each measures 60 degrees
180 degrees
180 degrees
It is an equilateral triangle that has 3 equal interior angles of 60 degrees
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
It is possible if neither of the angles in the triangle measures to 60 degrees
The 3 inside angles of any triangle add up to 180 degrees.
