March 11: Distance on a Graph

Today we learned how to determine distance between 2 points on a graph.

In order to determine the distance on a graph, we can use Pythagorean Theorem.  First we make a right triangle so that the distance we are looking for is the hypotenuse.  If we know the length of the legs (and because it's on a graph, we do!), we can easily solve for the missing side using a² + b² = c².

We did several examples in class and that sheet was secured in our math notebooks.

In each example, we drew a right triangle by using the segment given as the hypotenuse

.

Also, Progress Reports went out today, so please make sure those are SIGNED and RETURNED no later than FRIDAY, MARCH 13!  This is a homework assignment, so don't forget!
