What are angles that are formed opposite of each other when two lines intersect?
vertical angles
What lines are lines that form acute or obtuse angles at the point of intersection?
Vertical equal opposite angles are formed when lines intersect each other.
Are all angles of a parallelogram congruent?
All angles of a parallelogram are not necessarily congruent. A parallelogram means that the opposite sides run in straight lines that don't intersect. An example is a rectangle or square. Length of sides DO NOT determine if opposite angles are congruent. As long as opposite sides do not intersect each other at any point (if you continue to draw the lines), then the angles diagonal from each other are the same.
What is the two lines called that intersect at right angles?
They are called perpendicular lines that intersect each other at right angles.
What are two lines in the same plane that intersect at right angles?
Perpendicular lines intersect each other at right angles.
Angles formed opposite each other when two lines intersect?
Opposite angles are equal.
What are vertial angles?
They are the angles opposite each other when two lines intersect.
The angles opposite of each other when two lines intersect is called what?
They are simply called opposite angles.
What are angles that are formed opposite of each other when two lines intersect?
vertical angles
What are angles that are formed opposite each other when two lines intersect?
Vertical angles
Which angles are formed when two lines intersect each other?
opposite equal angles
What does opposite angles mean?
When 2 lines intersect, 4 angles are formed. The angles that are directly opposite to each other are called opposite angles.
What is angles formed by two intersecting lines that are opposite of each other?
A pair of opposite equal angles are formed when two lines intersect each other.
When two lines intersect they form four angles the angle across from each other are?
When two lines intersect, the angles across from each other are called vertically opposite angles, or just opposite angles. Opposite angles are equal to one another. See 'related links' below.
What are some vertically opposite angles?
Equal vertical opposite angles are created when straight lines intersect each other
What is formed opposite each other when 2 lines intersect?
Equal angles
What do you call angles formed opposite each other when two lines intersect?
perpendicular.
