### Example Question #8 : Distance Formula

Use distance formula to find the distance between the following two points.

**Possible Answers:**

**Correct answer:**

Use distance formula to find the distance between the following two points.

Distance formula is as follows:

Note that it doesn't matter which point is "1" and which point is "2" just so long as we remain consistent.

So, let's plug and chug.

So, our answer is

### Example Question #9 : Distance Formula

A triangle on a coordinate plane has the following vertices: . What is the perimeter of the triangle?

**Possible Answers:**

**Correct answer:**

Since we are asked to find the perimeter of the triangle, we will need to use the distance formula to find the length of each side. Recall the distance formula:

Start by finding the distance between the points :

Next, find the distance between .

Then, find the distance between .

Finally, add up the lengths of each side to find the perimeter of the triangle.

### Example Question #10 : Distance Formula

Find the distance between the points and .

**Possible Answers:**

**Correct answer:**

Find the distance between the points and .

To find the distance between two points, we will use distance formula (clever name). Distance formula can be thought of as a modified Pythagorean Theorem. What distance formula does is essentially treats our two points as the ends of a hypotenuse on a right triangle, then uses the two side lengths to find the hypotenuse.

Distance formula:

Pythagorean Theorem

If the connection isn't clear, don't worry, we can still solve for distance.

So our answer is 407
