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.

In the parallelogram below, BB' is the angle bisector of angle B and CC' is the angle bisector of angle C. Find the lengths x and y if the length of BC is equal to 10 meters. Solution to Problem 3: Note that the internal angles B and C are supplementary angles and their sum is equal to 180 degrees.

A good way to begin a proof is to think through a game plan that summarizes your basic argument or chain of logic. The following examples of parallelogram proofs show game plans followed by the resulting formal proofs. Proof 1 Here’s a game plan outlining how your thinking might go: Notice the congruent triangles. Always […]
