Hi,
find the measure of each side of isosceles ABC with AB=BC if AB=4y, BC=3y+2, and AC=3y.
4y=  3y+2, y = 2 ,  AB=BC = 8  and AC = 6

Find the measure of each side of ABC with vertices A(-1,5),B(6,1), and C(2,-6).
 {{{m =(y[2] - y[1])/(x[2] - x[1] )}}}
A(-1,5),
B(6,1),  m = -4/7  L of AB = sqrt(65)   | L = {{{sqrt ((x[1]-x[2])^2+(y[1]-y[2])^2))}}}
C(2,-6)  m = 7/4   L of AB= sqrt(65)  and AC, L of AB = sqrt(11^2 + 3^2) 0r sqrt(65 + 65)=  sqrt(11.4)
