6 Etensions 7. Any tilted segment tat connects two dots on dot paper can be te ypotenuse of a rigt triangle. You can use tis idea to draw segments of a given lengt. Te key is finding two square numbers wit a sum equal to te square of te lengt you want to draw. For eample, suppose you want to draw a segment wit lengt! units. You can draw a rigt triangle in wic te sum of te areas of te squares on te legs is. Te area of te square on te ypotenuse will be square units, so te lengt of te ypotenuse will be! units. Because and are square numbers, and + =, you can draw a rigt triangle wit legs of lengts and. a. To use tis metod, it elps to be familiar wit sums of square numbers. Copy and complete te addition table to sow te sums of pairs of square numbers For parts (b) (d) find two square numbers wit te given sum. b. 0 c. d. 89 For parts (e) (), draw tilted segments wit te given lengts on dot paper.
