# Proving the Parallelogram Side Theorem

Students were asked over to answer a question at academics and to declare what is most important for them to succeed. The one which response stood out from the rest was practice. People who usually are successful do not become successful by being born. They work hard and dedication their lives to succeeding. If you tend to accomplish your goals, keep this in mind! Below some question and answer examples that you could potentially use to supercharge your knowledge and gain insight that will help you to continue your school studies.

## Question:

Proving the Parallelogram Side Theorem

The proofing that ABCD is a parallelogram can be done through the parallelogram side theorem.

### What is the parallelogram side theorem?

It should be noted that the parallelogram side theorem simply means that the opposite sides of a parallelogram are equal and also parallel to each other.

Here, BCA and DAC are alternate interior angles. Also, AC denotes the reflexive property. Therefore, BC is the same as DA as they’re equal.
