LESSON and CLASSWORK 22 min The educator presents the lesson and allows learners to work at the problem at intervals. ( Thus incorporating classwork) Use the following to show the properties of quadrilaterals: The diagonals AC and BD of parallelogram ABCD intersect at point E. Measure the length of the diagonals. Measure the length of the line segments from E to each corner (BE, DE, CE, and AE). Use your protractor to measure the angles that the diagonals make with each other. What do you notice? Make a conjecture about the diagonals of a parallelogram. By construction, investigate sides, angles and diagonals in quadrilaterals, focusing on the diagonals of rectangles, squares, rhombi and kites.
