(number of sides) - (2) times (180) = sum of interior angle measurements
so for a triangle it is 3-2 which is 1 times 180 = 180, so the answer is 180 degrees
triangle sum conjecture is the sum of the measures of the angles in every triangle is 180 degrees
180 degrees
180 degrees
The 3 inside angles of any triangle add up to 180 degrees.
The sum of the 3 angles in any triangle always add up to 180 degrees
In a triangle, the sum of the measures of the angles is 180 degrees.
triangle sum conjecture is the sum of the measures of the angles in every triangle is 180 degrees
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
180 degrees
180 degrees
the sum of the triangle is 13.5
find the sum of the measures of the interior angles of 13-gon.
The 3 inside angles of any triangle add up to 180 degrees.
The sum of the three interior angles of a triangle always total 180 degrees.
The sum of the 3 angles in any triangle always add up to 180 degrees
Sum of angles is 180, not 90
The sum of the angles should equal 180
