A trapezoid has one pair of parallel sides, which are its bases. The other two sides, called the legs, are not parallel and can be either perpendicular or slanted, depending on the specific type of trapezoid. In summary, a trapezoid has one pair of parallel lines and zero perpendicular lines by definition.
If you mean what type of triangle has perpendicular lines then it is right angle triangle.
A triangle can have only three sides. No triangle can have 9 sides!
By definition, a parallelogram two separate pairs has parallel sides. The only type of parallelogram that has perpendicular sides is a rectangle. All others have non-perpendicular sides.
The triangle that has sides of different length is called a scalene triangle.
A`isoseles duhhh
A right triangle.
an iscoceles triangle
By using a pair of compasses or depending on what type of triangle it is creating a perpendicular line from one of its vertices to its opposite side.

a right triangle
Oh, what a happy little question! The type of triangle you're describing is called an equilateral triangle. In an equilateral triangle, all three angles are equal, and the angle bisectors are also the perpendicular bisectors of the sides, creating a beautiful balance in the painting of geometry.

This type of triangle is a scalene triangle
3 sides - such is the definition of triangle. Every triangle of any type has three sides.
