Question

1. drag and drop the words to the sentences. if two lines intersect, the four angles created by the intersecting lines all share the same __, but they are __ only if they are nonadjacent. choices: linear pairs, vertical angles, supplementary, sides, vertex.

Explanation:

Step1: Analyze the first blank

When two lines intersect, the four angles formed all share the same vertex. So the first blank should be filled with "vertex".

Step2: Analyze the second blank

The angles formed by intersecting lines: adjacent angles form linear pairs (supplementary), and non - adjacent angles are vertical angles. The second blank is about what the angles are when they are non - adjacent. So the second blank should be filled with "vertical angles".

Answer:

First blank: vertex; Second blank: vertical angles
