Time to review!​

Lets take a look at what happens when parallel lines are cut by a transversal... ​

​

Parallel Lines Cut by a Transversal​

​

​Linear Pairs

Two angles that form a line. The measure of both angles will add up to 180 degrees, making them supplementary. ​

​

Adjacent Angles​

Two angles that share a VERTEX and a SIDE

(side by side) .

​

Supplementary Angles​

When two or more angles have a sum of 180 degrees, making a straight line. ​

​

Multiple Choice

Using your knowledge of Supplementary Angles, determine the missing angle measure.

• 122 degrees

• 118 degrees

• 28 degrees

• 32 degrees

Complementary Angles​

When two or more angles have a sum of 90 degrees, making a right angle. ​

​

Multiple Choice

Using your knowledge of Complementary Angles, determine the missing angle measure.

• 70 degrees

• 72 degrees

• 58 degrees

• 66 degrees

Vertical Angles​

Angles that are OPPOSITE of each other when two lines intersect.

​

Vertical angles are CONGRUENT. ​

​

Multiple Choice

Choose the pair of vertical angles on the diagram shown.

• angles 1 and 6

• angles 2 and 3

• angles 1 and 8

• angles 7 and 2

Corresponding Angles​

Angles located at the same position of each intersection.

"Matching Corners"

​

Corresponding angles are CONGRUENT. ​

​

Multiple Choice

Choose the pair of corresponding angles on the diagram shown.

• angles 5 and 3

• angles 6 and 7

• angles 4 and 2

• angles 1 and 2

Alternate Interior Angles​

Angles INSIDE the parallel lines and on OPPOSITE sides of the transversal.

​

Alternate Interior angles are CONGRUENT. ​

​

Multiple Choice

Choose the pair of alternate interior angles on the diagram shown.

• angles 1 and 3

• angles 7 and 2

• angles 6 and 2

• angles 7 and 5

Alternate Exterior Angles​

Angles OUTSIDE the parallel lines and on OPPOSITE sides of the transversal.

​

Alternate Exterior angles are CONGRUENT. ​

​

Multiple Choice

Choose the pair of alternate exterior angles on the diagram shown.

• angles 1 and 3

• angles 4 and 3

• angles 6 and 5

• angles 6 and 2

Same - Side Interior Angles​

Angles INSIDE the parallel lines and on the SAME SIDE of the transversal.

​

Same - Side Interior angles are SUPPLEMENTARY. ​

​

Multiple Choice

Choose the pair of same - side interior angles on the diagram shown.

• angles 7 and 2

• angles 1 and 8

• angles 6 and 5

• angles 6 and 2
