This paper introduces in detail the drawing and solving process of a math application problem in junior one.
If you draw a picture, just draw it according to the coordinates. Can you find | AC | = [-4+2]? 0? 5+﹙3+ 1﹚? 0? 5]? 0? 5 = root number 20 | BC | = [-2]? 0? 5+﹙- 1﹚? 0? 5]? 0? 5 = radical number 5 | ab | = [| 4 |? 0? 5+3? 0? 5]? 0? 5 = root number 25 = 5 ∴| AC |? 0? 5+|BC|? 0? 5=|AB|? 0? The 5 ∴ triangle ABC is a right triangle with an area of s =1/2 | AC |×| BC | =1/2×10 = 5.
