Function Junction

Students plot the given points to make 3 different parallelograms in the coordinate plane. They must show the given theorem to be true that shows the quadrilateral is a parallelogram.

This lab uses angle-angle similarity to indirectly measure objects. By Function Junction.

This worksheet has students plot given points of a trapezoid. Then students must use midpoint formula to find the coordinates of the midsegment. Next, they verify that the segments are parallel using the formula for slope. Then they must use distance formula to verify the length of the midsegment.
