kyle's pythagorean growing post

Question 1:

Describe what a Pythagorean Triple is and use your perfect square chart from 1 squared to 10 squared to find another one other than 3,4,5.

A pythagorean triple is three numbers that are all perfect squares. Like 3 squared + 4 squared equals 5 squared. So, then it is 9 + 16 = 25. Another pythagorean triple from the perfect square chart is 6,8,10.

Question 2:

Using embeddable web 2.0, describe how to find the missing side of a Right Triangle using the Pythagorean Theorem, show how to solve both for a missing leg and the hypotenuse (note: you may use numerical examples ie. a=4 b=6 c=?)

Question 3:

Explain how to solve a Pythagoras word problem. Use one of the examples we covered in class (Worksheet A, B, LeFrog or Bonus Problem).

Mr. H jumped into a canoe to cross a river that runs east to west and is 20m wide. The current carried him down stream 8m before he reacked the other side. How far did he travel?

Question 4:

Now that you have seen many Pythagorean problems, create your own word problem.

Mr. Smith a 10ft. ladder and has to climb up a 8ft. wall. How far away fron the wall does Mr. Smith have to place the ladder?
