CD and EF are parallel to AB. They divide the area of PAB into three equal parts. If PE = 1, what is AC? I don't really know how to solve this. Is it similar triangles?
By similar triangles, AC = 1/3.
how did you find that? similar triangles? i have identified them but i'm not sure what to do next
Angle A = 90º
PA = AB
PE = 1
PC = √2
PA = √3
AC = √3 - √2
