Neither.
It forms 4 congruent angles and, as far as I am aware, no angels.
true
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
congruent congruent
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.

true
yes it does.Everyone knows that.
apex= True
Because if they werent, they would eventually form an angle.
yes they are because they meet to form at a right angle
Say angle 1 is 40 which means that if angle 3 is congruent then angle 3 is also 40 by definition of vertical angles. That would make angle 2 equal to 140 by definition of a linear pair and so angle 4 is congruent by vertical angles.
They are congruent angles.
yes, intersecting lines form two pairs of congruent angles
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
When two nonvertical straight lines intersect they form two congruent pair of nonadjacent angles, which are called the vertical angles (or vertical opposite angles). So that one of the three vertical angles is 30 degrees, and the other two angles have a measure of 150 degrees each, since they are adjacent to a 30 degrees angle.
Well, they're called vertically adjacent angles. They have the property that they are supplementary, because the non-adjacent sides form a straight line.
