Does a triangle only have one pair of parrell sides?
A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
What shape has exactly 2 perpendicular sides?
A right angled triangle is an example of a shape with exactly 2 perpendicular sides.
How many perpendicular sides does an obtuse triangle have?
An obtuse triangle is a triangle with one angle greater than 90 degrees. Since a perpendicular side is a side that forms a right angle with another side, an obtuse triangle can have 0 perpendicular sides if all its angles are obtuse. However, it can also have 1 perpendicular side if one of its angles is a right angle.
What is a perpendicular triangle?
a triangle with 2 sides
