A. Find the slope of the line containing the points (5, 8) and (5, 10). B. Then classify the line.
m = 2 and the line rises
m = 0 and the line is vertical
m = 0 and the line is horizontal
the slope is undefined and the line is vertical

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
