**Step-by-step explanation:**

yards is commonly used for large sparse area measurements

**Answer:**

B.

**Step-by-step explanation:**

**Answer:**

When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex

**Answer:**

=x2y−2xy2+7y2z

**Step-by-step explanation:**

Simplify

Let's simplify step-by-step.

4x2y+3y2z−2xy2−3x2y+4y2z

=4x2y+3y2z+−2xy2+−3x2y+4y2z

Combine Like Terms:

=4x2y+3y2z+−2xy2+−3x2y+4y2z

=(4x2y+−3x2y)+(−2xy2)+(3y2z+4y2z)

=x2y+−2xy2+7y2z

Answer:

=x2y−2xy2+7y2z

Answer:

1. Angle ABC = Angle DEF

2. Angle BCA = Angle EFD

3. Segment AC = Segment DF

4. Segment BA = Segment ED
