From geometry class we know that the sum of the measures of the interior angles of a triangle is 180 degrees, and since 41 + 76 + 63 = 180, the answer must be yes. But there’s more to this question ...

have three sides, therefore they have three angles. Interior angles in a triangle sum to a half turn (180˚). Quadrilaterals close quadrilateralA polygon with four straight sides. have four sides ...

These angles are created when two straight sides meet at a vertex. The angle sum of a triangle is 180 degrees. That means all triangles, no matter how differently formed, will have angles that add ...
