Wrong statement. Parallel lines don't always make vertical angles without the transversal, the line that passes through these lines. Without the transversal, we can't make the conclusion that parallel lines form vertical angles.
Perpendicular lines intersect each other at right angles which are 90 degrees Parallel lines never intersect each other and remain the equal distance apart. Intersecting lines form vertical opposite equal angles
Parallel lines cut by a transversal form congruent alternate interior angles.
Parallel lines do not meet and so do not form angles.
Vertical AngleThey form vertical angles
Only if the angles formed are right angles otherwise they form vertical opposite equal angles
Yes, a pair of intersecting lines always forms a pair of vertical angles.
4 angles
Vertical angles.
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
Perpendicular if they form right angles if not they form vertical opposite equal angles
Parallel lines do not meet and so cannot form an angle.
vertical angles
Yes, all perpendicular angles form 90 degree angles.
Vertical equal opposite angles are formed when lines intersect each other.
Parallel lines do not meet. Therefore they do not form any angles! So the angles (that do not exist) cannot add up to anything.
parallel
vertical angles
Triangles do not have parallel lines but as right angles triangles they do have perpendicular lines that meet at 90 degrees.
no perpendicular lines intersect one another to form 90 degree angles. parallel lines never intersect each other. perpendicular lines can NEVER be parallel
Lines that are neither parallel nor perpendicular.
two lines that are not parallel but are in the same plane.
A transversal
A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
