If necessary first fill-in the facts for pts E & F[br]Then for your trys:[br]1. Each time place pts C & B so their distance will be equal to EF.[br]2. record their coordinates[br]3. calculate the ∆x & ∆y[br]4. calculate/determine their distance.
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).
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).
3. The ∆x for the pair of pts. E and F or the pair of pts C and B was always equal to zero, explain why. Are there any useful take aways?
4.Is there another way to get the distance between two points on a coordinate plane when the points lie along a vertical line? Explain.
