Move pts. A & B so that AB (the distance between the 2 pts) is equal to EF. BUT you can't have the pts A & B line-up above or below pts E & F. 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 A & B so their distance will be equal to EF.
2. record their coordinates
3. calculate the ∆x & ∆y
4. calculate/determine their distance.
Short answer.
1. The symbol ∆x means "change in x". Explain how we calculate the ∆x and include an example in your explanation (not an ex. you have been provided with).
Short answer.
2. The symbol ∆y means "change in y". Explain how we calculate the ∆y and include an example in your explanation (not an ex. you have been provided with).
short answer
3. The ∆y for the pair of pts. E and F or the pair of pts A and B was always equal to zero, explain why. Are there any useful take aways?
Short answer
4. Is there another way to get the distance between two points on a coordinate plane when the points lie along a horizontal line? Explain.
