## Check your understanding of angles and parallel lines:

## 1. Choose the true statement:

1. z = y because they are co-interior angles

2. z = y because they are corresponding angles

3. z = y = 138° because z and y are co-interior and corresponding angles to 42°

4. z = y = 42° because z and y are alternate and corresponding angles to 42°

2. z = y because they are corresponding angles

3. z = y = 138° because z and y are co-interior and corresponding angles to 42°

4. z = y = 42° because z and y are alternate and corresponding angles to 42°

## 2. Choose the false statement:

1. p and q add up to 180° because q's vertically opposite angle is co-interior to p

2. q = 75° because its vertically opposite angle is corresponding to 75°

3. p and q equal 75° because they are vertically opposite and alternate angles to 75°

4. q's corresponding angle is vertically opposite 75°, so q = 75°

2. q = 75° because its vertically opposite angle is corresponding to 75°

3. p and q equal 75° because they are vertically opposite and alternate angles to 75°

4. q's corresponding angle is vertically opposite 75°, so q = 75°

## 3. k = 50° because

1. k's vertically opposite angle is co-interior to 130°

2. k is an alternate angle to 130°

3. k is a corresponding angle to 130°

4. 50 + 130 = 180

2. k is an alternate angle to 130°

3. k is a corresponding angle to 130°

4. 50 + 130 = 180
