Accepted Answer

$$\angle4$$ and $$\angle8$$

Answer

$$\angle3$$ and $$\angle8$$

Answer

$$\angle7$$ and $$\angle2$$

Answer

$$\angle7$$ and $$\angle8$$

Question 2

In this picture, two parallel lines are cut by a third line, called a transversal. How many vertical angle pairs can you find?

Accepted Answer

4 pairs of vertical angles

Answer

2 pairs of vertical angles

Answer

3 pairs of vertical angles

Answer

8 pairs of vertical angles

Question 3

In this picture, two parallel lines are cut by a third line, called a transversal. What is the maximum number of Linear Pairs of angles you can find?

Accepted Answer

8 Linear Pairs

Answer

2 Linear Pairs

Answer

4 Linear Pairs

Answer

6 Linear Pairs

Question 4

We assume that, since the lines are parallel, Corresponding Angles are congruent - for example $$\angle5\cong\angle1$$ . Check any box with Corresponding Angles.

Accepted Answer

$$\angle3\ and\ \angle7$$

Accepted Answer

$$\angle4\ and\ \angle8$$

Accepted Answer

$$\angle2\ and\ \angle6$$

Answer

$$\angle1\ and\ \angle2$$

Question 5

So, if $$\angle5\cong\angle1$$ , and $$\angle4\cong\angle1$$ , what can we conclude?

Accepted Answer

$$\angle5\cong\angle4$$ These are called Alternate Interior Angles. They are congruent if they are formed by parallel lines!

Answer

Sweet!

Answer

Cool.

Answer

Right on.

Question 6

If $$\angle5\ and\ \angle4$$ are one pair of Alternate Interior Angles, name the other pair of Alternate Interior Angles

Accepted Answer

$$\angle3\ and\ \angle6$$

Answer

$$\angle3\ and\ \angle2$$

Answer

$$\angle6\ and\ \angle8$$

Answer

$$\angle1\ and\ \angle9$$

Question 7

If $$\angle5\ and\ \angle4$$ and $$\angle3\ and\ \angle6$$ are both pairs of Alternate Interior Angles, click any Alternate Exterior Angles below.

Accepted Answer

$$\angle2\ and\ \angle7$$

Accepted Answer

$$\angle1\ and\ \angle8$$

Answer

$$\angle3\ and\ \angle2$$

Answer

$$\angle7\ and\ \angle8$$

Question 8

If these lines are parallel, $$\angle2\cong\angle6$$ because they're Corresponding Angles.
What is true about $$\angle2\ and\ \angle4$$ ?

Accepted Answer

They form a linear pair

Answer

They are congruent

Answer

They form vertical angles

Answer

They are non-adjacent angles

Question 9

If lines are parallel, same side interior angles like $$\angle4\ and\ \angle6$$ are supplementary. Name another pair of same side interior angles.

Accepted Answer

$$\angle3\ and\ \angle5$$

Answer

$$\angle3\ and\ \angle2$$

Answer

$$\angle5\ and\ \angle7$$

Answer

$$\angle2\ and\ \angle8$$
