I need help. Name a pair of vertical angle.
Can't see your diagram, but if two lines intersect
angles that share a vertex and are not adjacent to each other are vertical angles.
google the topic for examples. Your diagram must have a few.
Sure! Vertical angles are a pair of angles that are opposite each other when two lines intersect. To name a pair of vertical angles, we first need two intersecting lines. Let's call them line AB and line CD.
To find a pair of vertical angles, look at the points where line AB and line CD intersect. Let's assume that these points are named P and Q.
Now, draw two lines from point P to line CD, and from point Q to line AB, forming an "X" shape. This creates four angles.
Among these four angles, the pair of vertical angles will be the ones that are opposite each other. In this case, the pair of vertical angles would be angle APQ and angle BQP.
