How to solve for alternate interior angles
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.

WebSal constructs CF parallel to AB not equal to AB. We know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal). WebCorresponding Angles. When two lines are crossed by another line (called the Transversal ): In this example a and e are corresponding angles. Also: • b and f are corresponding angles. • c and g are corresponding angles. • d …
