Question

what is vertical and opposite angle?​

Answer 1

Answer:

Vertically opposite angles

Intersecting lines are lines that cross each other. The point where they meet is called a vertex.

When two lines intersect, the opposite (X) angles are equal.

Finding angles diagram

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.

X shape with overlapping diagonal lines creating equal angles

X shape with overlapping diagonal lines creating equal angles of 35°

If you know one angle in a pair of vertically opposite angles, the other will be the same.

Answer 2

Intersecting lines are lines that cross each other. The point where they meet is called a vertex. When two lines intersect, the opposite (X) angles are equal. These X angles are called vertically opposite angles because they are opposite each other at a vertex.
