if the triangle is a right angle it has 2 perpendicular line segments.
Line segments are lines so the answer is 3.
Three pairs. The line joining the midpoints of any two sides of a triangle is always parallel to the third side of the triangle (and half its length).
there are infinitely many segments in a line.
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.
If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
Line segments are lines so the answer is 3.
Each of the eight line segments is perpendicular to 2 line segments. So there are 8 pair in all.
A cube has 12 edges, and each edge is perpendicular to 4 other edges. However, since each perpendicular relationship is counted twice (once for each edge), the total number of unique perpendicular line segments in a cube is 12. Thus, a cube has 12 perpendicular line segments.
A box has 12 edges, and each edge is perpendicular to 4 other edges. However, each pair of perpendicular edges can be counted twice (once for each edge), so the total number of unique pairs of perpendicular line segments is 12. Thus, there are 12 perpendicular line segments in a box.
2 one horizontal and one vertical
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.

The isosceles triangle has one line of symmetry, the perpendicular bisector of the base
In the English alphabet, the uppercase letters that have perpendicular line segments are A, B, D, E, F, H, K, L, T, and Z. This totals to 10 uppercase letters. Each of these letters includes at least one pair of line segments that meet at a right angle.
Three pairs. The line joining the midpoints of any two sides of a triangle is always parallel to the third side of the triangle (and half its length).
25 o because sOme of them are perpendicular
