The 2 diagonals of a rhombus are perpendicular and they intersect each other at right angles
The 2 perpendicular sides of a right angle triangle intersect each other at right angles
It depends on how many lines intersect. An infinite amount.
Octagons have no perpendicular lines.
0 perpendicular lines. There are no 90 degree angles within a hexagon. Perpendicular lines meet at a right angle and sometimes they intersect.
Two lines that intersect will create2 pairs of equal angles and if the lines are perpendicular the angles created will be right angles
