It is called vertical.
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
When lines intersect, angle formed between them is Θ or 180-Θ.
90 degrees.
Two pairs of vertical angle formed by intersecting lines is a plus sign or an x. something that looks like this, but with the lines completely touching: +x
Intersecting lines that form a right angle are perpendicular lines.

When lines intersect, angle formed between them is Θ or 180-Θ.
Yes, that is the definition of perpendicular. 2 lines intersecting to form a right(90o) angle.
90 degrees.
Yes.

Vertical angles
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
Intersecting lines that form a right angle are perpendicular lines.
Vertical Angles or 4
Yes, that is the definition of perpendicular.
yes 90 degrees
