Arectangle is drawn on a coordinate plane. three vertices of the rectangle are points l(−7,14) , m(9,14) , and n(9,−12) . point p is the fourth vertex of the rectangle. how long is the side of the rectangle connecting points l and p?

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
