I am sure there are several; the simplest would be a right triangle, which means, a triangle with a right angle.
A trapezoid has only 1 pair of opposite parallel sides of different lengths.
Diamonds come in all shapes and sizes, which determine the number of perpendicular lines (assuming you are referring to the edges as the lines) so there is no one number of lines or perpendicular lines on a diamond.
