Example Question #1 : How To Find If Parallelograms Are Similar

A parallelogram has adjacent sides with the lengths of  and . Find a pair of possible adjacent side lengths for a similar parallelogram. 

Possible Answers:

 and 

 and 

 and 

 and 

Correct answer:

 and 

Explanation:

Since the two parallelogram are similar, each of the corresponding sides must have the same ratio. 

The ratio of the first parallelogram is:



Applying this ratio we are able to find the lengths of a similar parallelogram.

Example Question #2 : How To Find If Parallelograms Are Similar

A parallelogram has adjacent sides with the lengths of  and . Find a pair of possible adjacent side lengths for a similar parallelogram. 

Possible Answers:

Correct answer:

Explanation:

Since the two parallelogram are similar, each of the corresponding sides must have the same ratio. 

The ratio of the first parallelogram is:



Applying this ratio we are able to find the lengths of the second parallelogram.

Example Question #1 : How To Find If Parallelograms Are Similar

A parallelogram has adjacent sides with the lengths of  and . Find a pair of possible adjacent side lengths for a similar parallelogram. 

Possible Answers:

Correct answer:

Explanation:

Since the two parallelogram are similar, each of the corresponding sides must have the same ratio. 

The ratio of the first parallelogram is:



Thus by simplifying the ratio we can see the lengths of the similar triangle.
