trapezoid
Mutually perpendicular, adjacent sides.Mutually perpendicular, adjacent sides.Mutually perpendicular, adjacent sides.Mutually perpendicular, adjacent sides.
The adjacent sides of a square are perpendicular.
yes, in a sq. or a rec. , all adjacent sides are perpendicular
It doesn't need any in order to be a trapezoid. It can have a max of two pairs of perpendicular sides.
Adjacent sides of a rectangle are perpendicular.
Adjacent sides are perpendicular. Opposite sides are parallel.
Zero
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
The perpendicular adjacent sides in the triangle would be 3 sides. It is the basically horizonstal line next to a vertical line(perpendicular) if it was parallel adjacent then only two side of triangle /\ <-- parallel
"Adjacent" means next to each other. "Perpendicular" means at an angle of 90 degrees. Rectangles (this includes squares) have adjacent perpendicular sides. So do right triangles.
