Independent Practice_ Proving Parallelogram Properties asks students to replicate the proofs of parallelogram properties from scratch. Then the roles alternate until the item is completed. As I see that students have forged ahead, I return to the document camera and begin to reveal the proof one step at a time (lagging behind where students are) so that they can compare what they've done to what I've done. Therefore, I know I will have to find two pairs of congruent angles for AAS or ASA. Hence my choice to prove either triangles DMC and BMA congruent or triangles DMA and BMC. Metric units worksheet. We are building a body of knowledge, establishing truths that lead to more and more truths. 20 then 9 0 5. y =9 Solve. To a novice, it is not at all intuitive (nor should it be) why we would use triangle congruence to prove properties of parallelograms. After this, I have the A-B partner echo back what they've heard. Comparing rates worksheet. A parallelogram is 16 inches long and 4 inches high. Complementary and supplementary worksheet. So now that we have the givens, what we're trying to prove, and a plan of attack, I ask students to work independently to write the proof that Angle A is congruent to Angle C. I walk the room checking in on individual students and looking for things that may need clarification. Then I show myself drawing diagonal segment AC on the diagram. Geometry worksheets.
