8th Final - Transversal Angles And Triangle Theorems

Front

What are corresponding angles in the context of parallel lines and a transversal?

Back

Corresponding angles are pairs of angles that are in the same position on two different parallel lines cut by a transversal. They are equal in measure.

Front

What is the relationship between vertical angles?

Back

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

Front

How do you find the measure of an angle when given the measures of other angles in a transversal situation?

Back

You can use the properties of corresponding angles, alternate interior angles, and supplementary angles to find the measure of unknown angles.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

How do you determine if two lines are parallel based on angle measures?

Back

If a transversal intersects two lines and the corresponding angles are equal, then the lines are parallel.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

How can you find the value of x in angle problems?

Back

You can set up equations based on the relationships between the angles (like corresponding, vertical, or supplementary) and solve for x.

Front

What is the definition of an exterior angle in a triangle?

Back

An exterior angle is formed by one side of a triangle and the extension of an adjacent side. The measure of an exterior angle is equal to the sum of the measures of the two opposite interior angles.
