How Do You Find Supplemental & Complementary Angles?
Complementary and supplementary angles are similar in nature but different in the numerical value of the space that they occupy. Both types of angles come in pairs, and each set of angles can be either adjacent or separate. Furthermore, each duo of angles has a predetermined set value that the sum total must equal. For complementary angles, the set value is a right angle (90 degrees), and for complementary angles, that set value is a straight line (180 degrees). Place two boards on a pair of saw horses (one should have an angled cut at one end). Lay a board with an angled cut on top of a second plank that is of equal width and thickness. Make sure the top board is completely flush with the bottom board for its entire length. Mark a line on the bottom board, using the angled cut of the top piece as your template. Back the top board away from the mark. One inch is perfect; make sure that the pencil mark is clearly visible. Now, take your pencil and fill the one-inch gap with scratch mark
