Chantel's Pythagoras Growing Post

Part 1:
Pythagorean Triple:
The Pythagorean theorem states that the legs (a && b) and the hypotenuse (c) a right triangle obey the following relationship----> A2+B2=C2

Using the perfect square chart you can find Pythagorean Triples.

Part 2:
Problem B

You've just picked up a ground ball at first base, and you see the other
teams player towards third base. How far do you have to throw the ball
to get it from first base to the third base and throw the runner out?

PICTURE TIME! :D This picture shows the baseball diamond and where we
have to throw the ball!

Math work time:
a2=90 (2)
b2= 90(2)
c2= ??
a2+b2=c2
90(2) + 90(2) = C2
8100+8100= c2
8100+8100=16200
16200= c2

\/c2= \/ 16200 ( \/= square root sign)

c2= 127.28


PART 4:

Word Porblem;;

The letter of the day was L. Everyone in the class had to draw a L on there page.
Majolanoire wanted to know how long is it from the bottom of the L to the top.
The knew that one side of the L was 4cm and the other side was 3 cm.
How is she going to figure out how long it is from the bottom of the L to the top.
help Majolanoire figure it out and explain it the best you can.
