The Right Triangle. Perpendicular lines make a right angle.
It has a pair of perpendicular lines that meet at right angles to form the 90 degree angle of a right angle triangle.
a right triangle
no
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.
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
The Right Triangle. Perpendicular lines make a right angle.
No parallel lines but a right angle triangle has perpendicular lines.
None.
two if the triangle has a right angle
They are not. The perpendicular bisectors of a triangle, for example, intersect at the orthocentre of the triangle. So perpendicular lines can be intersecting and conversely.
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.
If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
Two
