None. Triangles do not have parallel sides
A trapezoid can have 4 equal sides and one right angle.
An angle must have 2 sides or it is no longer an angle.
Given the reference perspective of a specific angle the sides are are the adjacent sides and the opposite side If we have a right triangle the longest side (opposite the right angle) is the hypotenuse.
A right triangle in a plane is one in which one of the three angles is a right angle. It is obious that the two sides, making up the right angle, must be perpendicular. In symbols, if triangle ABC is a right triangle with angle B as the right angle, then the sides AB and BC are perpendicular.
