A right triangle does have perpendicular line because they can cross if the lines go on forever
A quadilateral is a 4 sided shape so if you talking about the square or a rectangle or a parralelogram no it does not have perpendicular sides BUT if you are talking about a trapezoid it does have pependicular side
HOPE THIS HELPS!!!!!!! ;-)
PLZ MARK ME AS BRAINLIEST!!!
You have to put what kinda if properties you use to slice the problem
