WebWhen two parallel lines are cut via a transversal, the pair of angles formed on which inner side of the parallel conducting, but on opponent sides starting the crosswise are called alternate interior aspects. WebIf a quadrilateral has all right angles and congruent sides, then it is a square. So both the original statement and its converse (switching the hypothesis and conclusion) are both true. Thus, we can combine it into an if and only if statement, It is a square if and only if it is a quadrilateral with all right angles and congruent sides. WebInterior Angles. (Angles found in a C -shaped or U -shaped figure) Interior angles are supplementary. Supplementary angles are angles that add up to 180˚. The sum of angles in a triangle is 180˚. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of interior angles of a quadrilateral is 360˚. grace lutheran shillington pa
