What is the relationship between two opposite angles?
When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal.

Are vertically opposite angles adjacent?
Adjacent Angles – Adjacent angles are two angles that have common arm and common vertex. Vertical Angles – Two lines intersect each other and form angles. The opposite angles are called vertically opposite angles. Adjacent Angles – There are two types of adjacent angles.
Why are vertically opposite angles equal?
Vertical angles are formed when two lines intersect each other. Out of the 4 angles that are formed, the angles that are opposite to each other are vertical angles. They are also referred to as ‘vertically opposite angles. These angles are always equal.
Which pairs are vertically opposite angles?
Angles a° and c° are also vertically opposite angles, so must be equal, which means they are 140° each. Answer: a = 140°, b = 40° and c = 140°. Note: They are also called Vertical Angles, which is just another way of saying the same thing.
How do you solve vertically opposite angles?
Are vertically opposite angles?
Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines. Vertically opposite angles are equal to each other. These are sometimes called vertical angles.
Can vertically opposite angles be right angles?
Yes, vertical angles can be right angles. When the two opposite vertical angles measure 90° each, then the vertical angles are said to be right angles.
How do you write vertically opposite angles?

What is the angle rule for vertically opposite angles?
Vertically opposite angles are equal to each other. These are sometimes called vertical angles. Here the two angles labelled ‘a’ are equal to one another because they are ‘vertically opposite’ at the same vertex.
How do you prove vertically opposite angles?
⇒∠AOC=180∘−180∘+∠BOD. ⇒∠AOC=∠BOD. From the figure, we can see that the angles ∠AOC and ∠BOD are vertically opposite angles. So, we have proved that if two lines intersect each other, then the vertically opposite angles are equal.
What are some examples of vertically opposite angles?
Vertically Opposite Angles Definition. Vertical in this case means they share the same corner point (vertex),not the usual meaning of up-down.
What does the word vertical and opposite angles mean?
The angles opposite each other when two lines cross. They are always equal. In this example a° and b° are vertically opposite angles. “Vertical” refers to the vertex (where they cross), NOT up/down. Try moving the points below. Notice that the 4 angles are actually two pairs of vertically opposite angles:
Why are vertically opposite angles always equal?
When two lines intersect, the opposite (X) angles are equal. In the diagram above, the two green angles are equal and the two yellow angles are equal. These X angles are called vertically opposite angles because they are opposite each other at a vertex . If you know one angle in a pair of vertically opposite angles, the other will be the same.
What are real life examples for vertical angles?
Examples of vertical angles in real life settings include the black and white railroad crossing signs found on roadways near railroads, open scissors and the letter “X.”. Other examples include the point where ceiling beams intersect in a somewhat x shape, and in a kite where two wooden sticks hold it together.
