None. Triangles do not have parallel sides
A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
A right-angled triangle can be an Isosceles Triangle, but NOT an equilateral triangle. An Isosceles triangle has two sides of equal length. They form the 90 degree (right angle). The hypotenuse is opposite the right angle, and is longer than the other two sides.
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.
A triangle with no right angle and sides of different lengths is a scalene triangle.
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 angle triangle has no parallel sides
a right angle triangle.
no triangles have parraell sides!
There are no parallel sides in a right angle triangle
A triangle has no parallel sides but in the form of a right angle triangle it has perpendicular lines that meet at right angles which is 90 degrees.
No triangle can have parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees
A right angle triangle has no parallel sides
A right angle triangle.
A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
It could be a right angle triangle
It fits the description of a right angle triangle
