vertical opposite equal angles
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
there both lines
Two lines are intersecting if they have exactly one point in common.
Yes. They're in the plane defined by the two intersecting lines.
Lines don't have endpoints, they extend indefinitely. Two line segments with a common endpoint form an angle.
Opposite angles are equivalent when formed by two intersecting lines
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
there both lines
Two lines are intersecting if they have exactly one point in common.
False. The angles can be formed by two skew lines intersecting a third line.
Yes. They're in the plane defined by the two intersecting lines.
vertical
It is called vertical.
