ISN Page Instructions

The Pythagorean Theorem ' the Distance Formula- your finished ISN page should look like the picture on the left

Glue your map onto page 54. The other page, pg 55 will show your work. Your map should look like the picture, with lots of different colors. As you are showing your work, make sure you show your work for each triangle in a different color. The first triangle is done for you as an example in the top part of the picture.

Glue the Pythagorean theorem notes on page 53 in your ISN. Glue the other pythagorean theorem booklet (the thick one with just pythagorean theorem on the front) onto page 52 and complete the problems in the booklet. The first one is done for you as an example.

Step 1

Next we will calculate distance between points in a different way. We have used the Pythagorean Theorem but there are 2 ways to do this and we will show the other way to do this, comparing it to the Pythagorean Theorem. Make sure your ISN page 56 looks like the picture to the left. Carefully graph the points (-8, 4) and (4, -4) and draw different colored lines. Feel free to copy down the work exactly as you see in the picture.

When you flip the flap down that says "Calculating Distance Between Two Points" it looks like this...

Here is an example of finding the distance between the points using the Pythagorean Theorem and the Distance Formula. Copy down the notes you see to the right using different colors. Then glue onto page 57 the Distance Formula booklet and calculate the other distances using the distance formula, like we did in these notes.
