Yes, a right triangle has only one set of perpendicular lines.
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.
Perpendicular. Bt ONLY right triangles contain perpendicular lines.
It is only applicable to a right angle triangle where the perpendicular lines meet at 90 degrees
Only when it is in the form of a right angle triangle that it will have perpendicular lines that meet at 90 degrees.
No parallel lines but a right angle triangle has perpendicular lines.
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.
No, but there can be perpendicular lines.
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
A triangle with a right angle in it is the only case in which a triangle can have perpendicular lines. Triangles themselves cannot be perpendictular unless you are referring to one of the sides being perpendicular to a certain line.
