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.

Still, we will get more specific in this section and discuss a special type of quadrilateral: Geometry Transformations Overview Common types of transformation Vectors Transformation using matrices. Geometry Perpendicular and parallel Overview Angles, parallel lines and transversals. Geometry Area Overview Parallelogram, triangles etc The surface area and the volume of pyramids, prisms, cylinders and cones.

The side labeled 4 x – 5 will not be used when solving for xbut will be used to solve for AD. The median of a trapezoid is parallel to the bases and is one-half of the sum of measures of the bases. The properties of parallelograms can be applied on rhombi. 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.

We will use the same method we used when solving for y: Together, the sum of the measure of those angles is because We probelm know that the remaining angles must be congruent because they are also opposite angles.

Therefore, we can set them equal to each other. M are congruent, we can define their measures with the same variable, x. This site uses cookies. Please read the ” Terms of Use “.

You know the opposite sides of a parallelogram are congruent, so set the opposite sides equal to one another.
