11D Angles formed by Parallel Lines and a Transversal

Front

What are Same-Side Interior Angles?

Back

Same-Side Interior Angles are pairs of angles that lie on the same side of the transversal and between the two parallel lines. They are supplementary, meaning their measures add up to 180 degrees.

Front

What are Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal. They are congruent, meaning they have equal measures.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie between the two parallel lines but on opposite sides of the transversal. They are congruent.

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 congruent.

Front

What is the relationship between Vertical Angles?

Back

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

Front

If angle 6 is 25 degrees, what is angle 7?

Back

Angle 7 is 155 degrees, as it is a Same-Side Interior Angle to angle 6.

Front

If angle 4 = x + 15 and angle 2 = 3x - 5, how do you find x?

Back

Set angle 4 equal to angle 2: x + 15 = 3x - 5. Solve for x to find x = 10.

Front

Which angles are NOT congruent to angle 5?

Back

Angle 6 is NOT congruent to angle 5.

Front

What is the sum of Same-Side Interior Angles?

Back

The sum of Same-Side Interior Angles is always 180 degrees.

Front

What is the measure of Corresponding Angles when two parallel lines are cut by a transversal?

Back

Corresponding Angles are equal in measure.
