### PROBLEM SOLVING 6-2 PROPERTIES OF PARALLELOGRAMS

It is a quadrilateral where both pairs of opposite sides are parallel. Quadrilateral Terminology Since this entire section is dedicated to the study of quadrilaterals, we will use some terminology that will help us describe specific pairs of lines, angles, and vertices of quadrilaterals. We can use the fact that the triangle has a right angle and that there are two congruent angles in it, in order to solve for x. Fill in your details below or click an icon to log in: QR and TS are opposite sides of the quadrilateral because they do not meet. You are commenting using your Twitter account. Find the value of x. QR and RS are consecutive sides because they meet at point R. 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. By the Polygon Interior Angles Sum Theorem, we know that all quadrilaterals have angle measures that add up to. J is a right angle, we can also determine that? Search Pre-Algebra All courses. If you forget this property, remember that a parallelogram has parallel lines, which have the interior angles on the same side of the transversal supplementary. Find x and y.

One angle is obtuse and the other angle is acute. We will use the same method we used when solving for y: Leave a Reply Cancel reply Enter your comment here The needed property is that the oroblem bisect each other – a property held by both parallelograms and rhombuses.

## Properties of parallelograms

If we have a parallelogram where all sides are congruent then we have what is called a rhombus. There are six important properties of parallelograms to know: M are congruent, we can define their measures with the same variable, x. In this problem, the trapezoid is divided into two right triangles and a rectangle. Geometry Area Overview Parallelogram, triangles etc The surface area and the volume of pyramids, prisms, cylinders and cones.

It is a quadrilateral where both pairs of opposite sides are parallel. One special kind of polygons is called a parallelogram.

Every parallelogram will have only two diagonals. The re-posting of materials in part or whole from this site to the Internet is copyright violation and is not considered “fair use” for educators. QR and TS are opposite sides of the quadrilateral because they do not meet. We can use the fact that the triangle has a right angle and that there are two congruent angles in it, in order to solve for x. If the legs are congruent we have what is called an isosceles trapezoid.

After examining the diagram, we realize that it will be easier to solve for x first because y is used in the same expression as x in?

J is a right angle, we can also determine that? Find the number of units in BD in simplest radical form.

Segments BE and DE are also congruent.
