Two angles must be equal and when added to the third angle should total 180 degrees.
What total do you mean? area? volume? or other mathematical terminologies? or do you mean the total sides of an isosceles triangle? LOL :)) well its angle total will have to be 180 no matter what because each triangle has an interior angle sum of 180. SO yea...................... that is why. :)
The 4 interior angles add up to 360 degrees
The interior angle of an n-sided polygon total 90(2n - 4) degrees
900 degrees
The interior angles of ANY trapezium sum to 360 degrees.
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.

A trapezoid is a quadrilateral and like all quadrilaterals it will have a total sum of 360 degrees of interior angles.
The sum of the interior angles is 360 degrees.
Each interior angle is 120o making the total 720o.
A point has no interior and so cannot have interior angles.
The interior angle of an n-sided polygon total 90(2n - 4) degrees
108o
900 degrees
