What does vertical angles mean?
Vertical Angles are a pair of nonadjacent anglesopposite each other formed when two lines cross.Vertical angles are two angles opposite of each other. Vertical angles will also always have equal angles.
What is formed by perpendicular lines?
Perpendicular lines formed right angles.
Two nonadjacent angles formed by two intersecting line are called?
Two angles that aren't adjacent but are formed by intersecting lines are called vertical angles. Their angle measures are always equal.
How is AB is perpendicular to CD How many 90 and deg angles are formed by the intersection?
If AB is a perpendicular bisector of CD then four 90 degreee angles are formed.
When chords intersect in a circle the vertical angles formed intercept conruent arcs always sometimes never?
Sometimes
What is the opposite angles formed by the intersection of two lines?
They are equal opposite vertical angles and if the lines are perpendicular to each other then 90 degree angles are formed.
What happens when two lines intersept?
When two lines intercept equal opposite vertical angles are formed and if the lines are perpendicular then right angles are formed
Which types of angles are always congruent?
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
If two lines intersect to form adjacent angles then the lines are perpendicular?
Only if the angles formed are right angles otherwise they form vertical opposite equal angles
What does vertical angles mean?

What is formed by perpendicular lines?
Perpendicular lines formed right angles.
ARE Acute angles are formed by perpendicular lines?
No. Perpendicular lines for right angles. That is why they are called perpendicular.
What are angles opposite one another at the intersection of two lines?
They are said to be perpendicular. Or, if you wanted an example of a pair of such lines, one example is a plus sign.
What are vertivle angles?
I think you mean vertical angles. Vertical angles are formed by two intersecting lines that make what looks like an X. Vertical angles are the two angles that are across from each other, either the top and bottom 2 angles or the left and right 2 angles. Vertical angles are also always congruent!
What angles are formed by lines that are perpendicular?
90 degree angles.
What are formed by perpendicular lines?
90* angles
Two nonadjacent angles formed by two intersecting line are called?
Two angles that aren't adjacent but are formed by intersecting lines are called vertical angles. Their angle measures are always equal.
