Which statement is true regarding the parallel and perpendicular lines in the diagram? k n and w m k n and n m w n and n m w n and w m

The length of triangle base is 26. a line, which is parallel to the base divides the triangle into two equal area parts. find the length of the segment between triangle legs.

Write an equation of the line that passes through the point (2, 3) and is perpendicular to the line x = -1. a) y = 1 b) y = 3 c) y = 0 eliminate d) y = -3

I'm confused on how to solve the triangle. can someone me ?
