Perpendicular lines.

Theorem 3.9. If two lines are perpendicular, then they intersect to form 4 right angles. You would do a proof by using your hands.
The sides if a square or rectangle?
If you form the digits with a seven-segment LED display, then all of the digits except '1' have perpendicular lines.
Perpendicular lines.
perpendicular
false
No because they will form 4 right angles of 90 degrees

Theorem 3.9. If two lines are perpendicular, then they intersect to form 4 right angles. You would do a proof by using your hands.
The sides if a square or rectangle?
By definition, any lines/segments that are perpendicular to each other either do, or (in the case of non-intersecting segments) would, intersect each other at right angles. A right angle being a 90* angle. Therefore, perpendicular, intersecting line segments will form 4 90* angles.
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
Normally, none.
If you form the digits with a seven-segment LED display, then all of the digits except '1' have perpendicular lines.
