Flashcardizz game: Identifying Vertical angles and linear pairs

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles whose non-common sides form a straight line. The measures of angles in a linear pair add up to 180 degrees.

Front

How do you identify vertical angles in a diagram?

Back

Vertical angles can be identified as the pairs of angles that are opposite each other at the intersection of two lines.

Front

What is the relationship between the measures of angles in a linear pair?

Back

The measures of angles in a linear pair always add up to 180 degrees.

Front

Can vertical angles be adjacent?

Back

No, vertical angles are never adjacent; they are opposite angles formed by the intersection of two lines.

Front

If ∠AOD and ∠AOC are adjacent angles, what can be said about their relationship?

Back

If ∠AOD and ∠AOC are adjacent angles, they share a common side and their measures can be added together to find the total angle formed.

Front

What are the pairs of vertical angles formed by two intersecting lines?

Back

If two lines intersect, the pairs of vertical angles are formed by the angles opposite each other at the intersection.

Front

If ∠1 and ∠4 are vertical angles, what can be concluded about their measures?

Back

If ∠1 and ∠4 are vertical angles, then their measures are equal.

Front

What is the sum of the measures of angles in a linear pair?

Back

The sum of the measures of angles in a linear pair is always 180 degrees.

Front

How can you determine if two angles are a linear pair?

Back

Two angles are a linear pair if they are adjacent and their non-common sides form a straight line.
