### PROBLEM SOLVING 6-2 PROPERTIES OF PARALLELOGRAMS

By the Polygon Interior Angles Sum Theorem, we know that all quadrilaterals have angle measures that add up to. The following problems will demonstrate strategies and hints for solving numerical and algebraic problems dealing with quadrilaterals. Email required Address never made public. In this problem, the trapezoid is divided into two right triangles and a rectangle. Use your algebra skills!

While a diagram should never be used as proof of the dimensions of a figure, the parallelogram figure will show you that these two angles cannot be equal to one another.

One angle is obtuse and the other angle is acute. We know that segments IJ and GJ are congruent because they are bisected by the opposite diagonal. Each diagonal of a parallelogram separates it into two congruent triangles. Notify me of new comments via email. Think about what AREA entails which is the use of the base and height of a triangle. If we have a quadrilateral where one pair and only one pair of sides are parallel then we have what is called a trapezoid.

The diagonals of a parallelogram bisect each other. In an isosceles trapezoid the diagonals are always congruent. Parallel lines are everywhere equidistant, making vertical height measurements within the trapezoid equal.

Consecutive Angles Two angles whose vertices are the endpoints of the same side are called consecutive angles. Find the value of x.

This question asks for the angle measure, not for just the value of x. Segments BE and DE are also congruent.

QR and TS are opposite sides of the quadrilateral because they do not meet. The parallel sides are called bases while the nonparallel sides are called legs.
