A board that is 16

feet long is cut into three pieces. If the length of the first piece is

3

5

6

feet and the length of the second piece is

4

5

6

feet, how long is the remaining piece of board?

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
