1. Opposite sides are \( \qquad \) . 2. Opposite sides \( \qquad \) . 3. Opposite angles \( \qquad \) 4. Consecutive angles \( \qquad \) 5. Diagonals \( \qquad \) each other. 6. All angles are \( \qquad \) angles. 7. Diagonals are \( \qquad \) a congruent, parallel, parallel, congruent, supplementary, bisect, right, congruent b parallel, congruent, supplementary, congruent, bisect, right, congruent c parallel, congruent, congruent, supplementary, bisect, right, congruent

To fill in the blanks, we need to understand the properties of a parallelogram. Here are the properties we can use to complete the statements: 1. Opposite sides are **parallel**. 2. Opposite sides **are congruent**. 3. Opposite angles **are congruent**. 4. Consecutive angles **are supplementary**. 5. Diagonals **bisect** each other. 6. All angles are **right** angles (this is true for rectangles, which are a specific type of parallelogram). 7. Diagonals are **congruent** (this is also true for rectangles). Now, let's match these properties with the options provided: - For statement 1, we use **parallel**. - For statement 2, we use **congruent**. - For statement 3, we use **congruent**. - For statement 4, we use **supplementary**. - For statement 5, we use **bisect**. - For statement 6, we use **right**. - For statement 7, we use **congruent**. Now, let's check which option matches these answers: - a: parallel, congruent, supplementary, congruent, bisect, right, congruent - b: parallel, congruent, supplementary, congruent, bisect, right, congruent - c: parallel, congruent, congruent, supplementary, bisect, right, congruent The correct option is **b**: 1. Opposite sides are **parallel**. 2. Opposite sides **are congruent**. 3. Opposite angles **are congruent**. 4. Consecutive angles **are supplementary**. 5. Diagonals **bisect** each other. 6. All angles are **right** angles. 7. Diagonals are **congruent**.
