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.
Only once at, a right angle. Paralell lines never meet.
Two of the three lines in a right triangle are perpendicular. Perpendicular lines meet at a 90 degree angle (also called a right angle). All right angle triangles have one right angle.
No parallel lines but a right angle triangle has perpendicular lines.
right triangle
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.
Because a right angle has to have 2 lines.
If you mean what type of triangle has perpendicular lines then it is right angle triangle.
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
A right angle is formed when two lines meet at an angle whose measure is 90 degrees. A right triangle is a triangle in which one angle is a right angle. (Note: there cannot be more than one.)
two if the triangle has a right angle
