no they don't have perpindicular lines
No, not all diagonals are perpendicular in all parallelograms. In general parallelograms, the diagonals bisect each other but are not necessarily perpendicular. However, in specific types of parallelograms, such as rhombuses, the diagonals are indeed perpendicular. Thus, the property of perpendicular diagonals is not a characteristic of all parallelograms.
No.
Equilateral parallelograms.
Most parallelograms do not have any lines of symmetry. The only parallelograms that can have lines of symmetry are squares, rectangles, and rhombuses.
parallelograms have two sets of parallel lines trapezoids do not
= 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.
Perpendicular lines intersect.
These lines are perpendicular: _|
Lines that aren't perpendicular
PERPENDICULAR
perpendicular.
Lines that intersect at 90 degrees are perpendicular lines
