### PROBLEM SOLVING 6-2 PROPERTIES OF PARALLELOGRAMS

Geometry Perpendicular and parallel Overview Angles, parallel lines and transversals. Menu Skip to content Home About Contact. Notice that several triangles can have base AD. 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? Consecutive Angles Two angles whose vertices are the endpoints of the same side are called consecutive angles. Search Pre-Algebra All courses.

The following problems will demonstrate strategies and hints for solving numerical and algebraic problems dealing with quadrilaterals. If we have a quadrilateral where one pair and only one pair of sides are parallel then we have what is called a trapezoid.

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. Therefore, we can set them equal to each other. Geometry Similarity Overview Polygons Triangles. If one angle is right, then all angles are right.

Geometry Perpendicular and parallel Overview Angles, parallel lines and transversals. We know that segments IJ and GJ are congruent because they are bisected by the opposite diagonal.

We will use the same method we used when solving for y: Leave a Reply Cancel reply Enter your comment here If we have a parallelogram where all sides are congruent then we have what is called a rhombus. Consecutive Angles Two angles whose vertices are the endpoints of the same side are called consecutive angles. Menu Skip to content Home About Contact. QR and RS are consecutive sides because they meet at point R. You know the opposite sides of a parallelogram are congruent, so set the opposite sides equal to one another.

Each diagonal of a parallelogram separates it into two congruent triangles. This question asks for the angle measure, not for just the value of x. By the Polygon Interior Angles Sum Theorem, we know that all quadrilaterals have angle measures that add up to. Geometry Right triangles and trigonometry Overview Mean and geometry The converse of the Pythagorean theorem and special triangles. Think about what AREA entails which is the use of the base and height of a triangle.

Use your algebra skills! Geometry Transformations Overview Common types of transformation Vectors Transformation using matrices. 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.

M are congruent, we can define their measures with the same variable, x. The parallel sides are called bases while the nonparallel sides are called legs.

QR and TS are opposite sides of the quadrilateral because they do not meet. You are commenting using your Google account.

Find x and y. Parallel lines are everywhere equidistant, making vertical height measurements within the trapezoid equal.
