Acute Pythagorean
Obtuse Pythagorean
Right Pythagorean


Certain right triangles have properties that
allow you to use shortcuts to determine side
lengths without using the Pythagorean
Theorem
These are called “special right triangles”

Create a square and fold one corner to
middle, what did you form?
Isosceles triangle
Each angle of square equals _______________?
So half equals?
Pg. 499
Now create a right triangle, but all sides are
different lengths
