1. Pythagorean Theorem

2. Water Demonstration

3. Review --- which side lengths belong to a right triangle??
6, 9, 13
8, 15, 17

4. Review: Isolate the variable
3) 4)

5. Review: simplify the radical
5) 6)

6. Solve for the missing side, part 1
When C is missing….
Step 1:
Find the sum of a2 and b2
Step 2:
If the sum in step one is c2,
Then we must “undo” the
squaring of c. (Square Root!)
Step 3: Simplify

7. Solve for the missing side, part 2
When a or b is missing….
Step 1:
Substitute what you do know into a2 + b2 = c2
and square
Step 2:
Isolate the missing term in the equation b2 = c2 –a2
Step 3:
Find the difference
Step 4:
“Undo” the square & Simplify
