8 Lesson 30: Solving for Missing Transversal Angles

Front

What are vertical angles?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal.

Front

What is the relationship between corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

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

Back

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

Front

What is the sum of angles on a straight line?

Back

The sum of angles on a straight line is 180 degrees.

Front

What is the sum of angles in a triangle?

Back

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

Front

If two angles are supplementary, what is their relationship?

Back

Two angles are supplementary if their sum is 180 degrees.

Front

If two angles are complementary, what is their relationship?

Back

Two angles are complementary if their sum is 90 degrees.

Front

What is a transversal?

Back

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

Front

How do you identify alternate interior angles?

Back

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