If it's a right triangle, then one.There is no other way to have a perpendicular angle in a triangle without it being 90 degrees, or right.
The 2 perpendicular sides of a right angle triangle intersect each other at right angles
A scalene triangle, which has all sides of different lengths and all angles of different measures, can have zero, one, or two perpendicular lines, depending on its specific angles. However, it is important to note that a scalene triangle cannot have all three sides forming right angles since that would contradict its definition. Therefore, the number of perpendicular lines in a scalene triangle is not fixed and can vary.
A right angled triangle.
They meet at right angles
Perpendicular lines intersect at right angles.
The 2 perpendicular sides of a right angle triangle intersect each other at right angles
It has a pair of perpendicular lines that meet at right angles to form the 90 degree angle of a right angle triangle.
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.
Perpendicular means meeting at a right angle. A right triangle has 2 sides that are perpendicular, so it has 1 pair of sides that are perpendicular They are known as the "legs" of the right triangle.
a right triangle
Perpendicular.
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.
There are twp perpendicular edges in a triangular prism. See if you draw a triangle you'll have two angles or edges that are the same length. That is if you draw a standard triangle.
If you have a triangle then one of the sides cannot be perpendicular to the other two. It is true for a square but it is impossible with a triangle. Definition of perpendicular: Being at right angles to the horizontal; vertical.
They meet at right angles
A right angled triangle.
There are 3 angles in a triangle
