They equal vertical angles
star
Vertical equal opposite angles are formed when lines intersect each other.
equal
Corresponding angles are equal and are formed when a transversal line cuts through parallel lines
Vertical-A+I believe the answer would be 2 ninety degree angles
When two perpendicular lines cross you get four equal angles of 90 degrees.
The angles formed are supplementary, equal corresponding and equal alternate angles
Four of them.
When two lines intercept equal opposite vertical angles are formed and if the lines are perpendicular then right angles are formed
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
They are equal opposite vertical angles and if the lines are perpendicular to each other then 90 degree angles are formed.
Equal angles.
Equal opposite angles.
vertical angles are formed when two lines cross.
