Geometry Angle Relationships PRACTICE 11.04.24

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions relative to a transversal that intersects two parallel lines. They are equal in measure.

Front

What does it mean for angles to be adjacent?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

What does it mean for angles to be supplementary?

Back

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

Front

How do you find the value of x in angle relationships?

Back

To find the value of x, set up an equation based on the relationships between the angles (e.g., supplementary, complementary, or equal) and solve for x.

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 vertical angles?

Back

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

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

How do you identify 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

What is the formula for finding the measure of an exterior angle of a triangle?

Back

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

Front

What is the definition of a transversal?

Back

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