The document provides instructions for drawing a right triangle with an altitude to the hypotenuse, dividing it into three smaller triangles. It asks the reader to: 1) Draw the right triangle and label its sides X, Y, Z, with Z being the right angle. 2) Draw the altitude to the hypotenuse, labeling the point of intersection B. 3) Name the three triangles created. 4) Explain what is known about the properties of these three triangles.
