Given the right triangle with sides a, b, and hypotenuse c:
Make three copies and rotate and arrange them, thus the area of large square is c2. The sides of the small enclosed square are b − a.	Move the triangle in the upper right to the lower left to complete the "upright" rectangle on the left. Move the triangle in the upper left to the lower right to complete the rectangle on the right. Extend the right side of the small square downward. Now there are two squares with areas a2 and b2 that are formed from the original big square with side c with area c2
Therefore, c2 = a2 + b2

This course is designed to meet the needs of the Adult Degree Program and Distance Education students at Southwestern Adventist University. The structure has been adapted for the distance education environment from an on-campus course.  The mathematics you will be studying is the same as and the assignments and tests are virtually identical to the grading opportunities students attending classes at Southwestern Adventist University find. I wish you the best success as you study this material.  May you find this mathematics interesting and enjoyable!  If I can, as a teacher, help you in successfully completing the requirements and earning a great grade, then I am more than happy to work with you towards that end.
