Consecutive Angles Of A Parallelogram Math

Consecutive angles are supplementary if you start at any angle and go around the parallelogram in either direction each pair of angles you encounter always are supplementary they add to 180. So if opposite sides of a quadrilateral are parallel then the quadrilateral is a parallelogram. Add to and opposite angles are congruent i e.

Consecutive angles of a parallelogram math. What are the measures of both angles. The bisectors of any two consecutive angles of a parallelogram are perpendicular. Parallelograms have opposite interior angles that are congruent and the diagonals of a parallelogram bisect each other. In a parallelogram consecutive angles are supplementary i e.

A parallelogram is a quadrilateral that has opposite sides that are parallel. The consecutive angles of a parallelogram measures a x 30 and b 4x. A parallelogram is a rhombus. Using these properties we can write a system of equations.

This is a result of the line bd being a transversal of the parallel lines ab and cd.
