# C. Distance between two points on a coordinate plane

## Move endpoints C & D so that CD (the distance between the 2 pts - which is equal to the length of segment CD) is equal to EF. You will fill in the table located below the grid. You will also answer some questions & make some observations

## Table directions

If necessary first fill-in the facts for pts E & F
Then for your trys:
1. Each time place pts C & D so their distance will be equal to EF.
2. record their coordinates
3. calculate the ∆x & ∆y
4. calculate/determine their distance.
**FYI: sqrt is the abbreviation for "square root of" **

## short answer

1. The ∆x and ∆y for the pair of pts. in these examples were never equal to zero. What are your take aways?

## Short answer

2. What did we need to do in order to get the length of the segments in these examples? (FYI - the length of a segment and the distance between two points will be equal).

## Short answer

3. Is there another way to get the distance between two points on a coordinate plane? Explain.
