Given:
r, s, t are midpoints of ab, bc, and ca. if rs = 5, then ac =

AC= 10

Step-by-step explanation:

Given: In ΔABC , R,S,T are the midpoints of AB, BC and CA

          length of RS= 5

To find : length of AC

Solution: By mid segment theorem which state that

In a triangle, the segment joining the midpoints of any two sides will be parallel to the third side and half of its length.

using this theorem , RS parallel to AC and

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
