Given the length (in feet) of side AB and the internal angle D of the parallelogram below, find its height h and the length of side BC given that the area of the parallelogram is equal to 1000 feet 2. Solution to Problem 2: Since it is a parallelogram internal angles A and D are supplementary and their sum is equal to 180 degrees.

Classify Quadrilateral as parallelogram A classic activity: have the students construct a quadrilateral and its midpoints, then create an inscribed quadrilateral. Then ask the students to measure the angles, sides etc.. of inscribed shape and use the measurements to classify the shape (parallelogram).
2.1 Adding Forces by the Parallelogram Law Example 1, page 1 of 4 1. Determine the magnitude and direction of the resultant of the forces shown. 30° 150 N 200 N 30° 200 N 150 N 30° Construct a parallelogram by drawing two lines. Each line starts at the tip of one vector Tip and is parallel to the other vector. Parallel Tip 1
How to solve problems on the parallelogram sides measures - Examples Problem 1 Find the perimeter of the parallelogram, if its sides are 7 cm and 12 cm long. Solution The opposite sides of the parallelogram are congruent, therefore the parallelogram four sides measures are 7 cm, 12 cm, 7 cm and 12 cm.
How to solve problems on the angles of parallelograms - Examples In this lesson you will find the solutions of some typical problems on the angles of parallelograms. To solve this kind of problems use the basic properties of parallelograms: - the opposite angles of a parallelogram are congruent
Example: A parallelogram has a base of 12 cm and a side length of 6 cm, what is its Perimeter? Perimeter = 2 × (12 cm + 6 cm) = 2 × 18 cm = 36 cm. Diagonals of a Parallelogram. The diagonals of a parallelogram bisect each other. In other words the diagonals intersect each other at the half-way point.
Since FGHJ is a parallelogram, we can use the fact that consecutive angles in a parallelogram are supplementary to find the measure of ∠3. Supplementary angles add up to 180°, which means that: m∠3 + m∠4 = 180° m∠3 + 90 = 180° m∠3 = 90° Now we can use the fact that opposite angles in a parallelogram are congruent.
A typical problem involving the area and perimeter of a parallelogram gives us the area, perimeter and/or base, height, and an angle of the parallelogram. We may also be given a relationship between the area and perimeter or between the base and height of the parallelogram. We need to calculate some of these quantities given information about the others.
