What is Pythagorean Theorem?
A theorem stating that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other sides.

But what does it do for us?
Pythagorean Theorem allows us to find unknown measures of side lengths for right triangles.
5
Right Triangles
These always have three sides - two legs and a hypotenuse. The two legs are always shorter than the hyptenuse and the hypotenuse is always found across from the right angle.

Multiple Choice
Find the missing side (hint: use what you know about estimating irrational numbers to answer)
11
Distance Between Two Points
We can use the slope between two points to create the legs of a right triangle.
12
Distance Between Two Points
We can count the rise and the run.
That will become the legs of the right triangle we are creating.
Using Pythagorean Theorem, we can determine the distance between the two points by finding the length of the missing hypotenuse.

Pythagorean Theorem in the Real-World
-We can use Pythagorean Theorem to do more than just find the hypotenuse of right triangles and the distance between two points.
-We can apply those skills to do things like find out how long things like shadows are, how tall buildings are, or find the shortest distance to a place.
