Find and record the coordinates of the endpoints of AB and the lengths of the horizontal and vertical sides of the right triangle.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
