an iscoceles triangle
equilateral triangle
it is a right triangle because a rhombus' diagonals are perpendicular
If only two sides of a triangle are the same length it is an isosceles triangle. If all three sides are the same length it is an equilateral triangle.
scalene triangle
A triangle with three equal sides and three equal angles is called an equilateral triangle.
A right triangle.
A`isoseles duhhh
a right triangle
A triangle, no matter the type, can never have any parallel sides. To try this out, draw any two parallel lines on a sheet of paper and try to make a triangle out of it.
Construct a scalene triangle and then from each of its vertices draw a straight line that is perpendicular to its opposite side and where these 3 straight lines intersect it is the orthocenter of the triangle. The position of the orthocenter can vary depending on what type of triangle it.
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!
This type of triangle is a scalene triangle

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