### Pythagorean Theorem

Mr. Harbeck was

These are the four artifacts that were found in his backpack:

1) How are these artifacts linked?

Pythagoras figured out a theorem, which was a2+b2=c2. That's why it's called the Pythagorean Theorem. In his theorem, he used right triangles and squares to figure out some math problems.

Here are some vocabulary that was found on a piece of paper:

a) The legs are the two sides of a right triangle, that make a 90 degree angle.

The Pythagorean Theorem is a2+b2=c2. It's basically a formula to calculate a side of a right triangle. When using this theorem, you'll be dealing with triangles, squares, areas, perimeters, and square roots. If you read my post carefully, you'll understand, but if not, I recommend that you find more sources.

I think Mr. Harbeck cares about this unit, so we could be prepared for Grade 9 Math, next year. I also have a feeling that we're going to be dealing with this stuff in the future.

Problem #2

17 + 30.232 + 24.999 = 72.231 cm

5) Here's my video with Elmane. Zerlina's part of our group but she couldn't do it with us.

*supposed*to teach us a new unit, but he had an accident, and unfortunately forgot everything. So here's what I think the whole unit is about.These are the four artifacts that were found in his backpack:

1) How are these artifacts linked?

a) The statue of a man's head is Pythagoras.

b) The shape with a little square in the corner, is called a right triangle.c) The square is simply, just a square.

- all sides are equal

- you could tell if all sides are equal if there are four ticks on them

- has 4 right angles

- has 4 sides

- has a line of symetry

- two right triangles make a square

d) The formula is called the Pythagorean Theorem.Pythagoras figured out a theorem, which was a2+b2=c2. That's why it's called the Pythagorean Theorem. In his theorem, he used right triangles and squares to figure out some math problems.

Here are some vocabulary that was found on a piece of paper:

a) legs

b) hypotenuse

c) R. A. T.

d) Greek

e) theorem

2) How could you use the vocabulary to explain the artifacts?

a) The legs are the two sides of a right triangle, that make a 90 degree angle.

b) The hypotenuse is the longest side of a right triangle, and/or the side that is opposite of the 90 degree angle.

c) A R. A. T. is a right angled triangle. Basically, a right triangle. (same thing)

d) Pythagoras is Greek.

e) Pythagoras' theorem is a2+b2=c2.

*label all three sides, a, b and c.*

3) What is the Pythagorean Theorem, and why does Mr. Harbeck care, in Grade 8 Math?

The Pythagorean Theorem is a2+b2=c2. It's basically a formula to calculate a side of a right triangle. When using this theorem, you'll be dealing with triangles, squares, areas, perimeters, and square roots. If you read my post carefully, you'll understand, but if not, I recommend that you find more sources.

4) Here are 2 problems that I'll show you how to solve:

Problem #1

This diagram shows the game plans for a game designed by Harbeck Toys INC. The board is made up of a square and 4 identical right triangles.

If the central square has an area of 225 square centimetres, what is the perimeter of the board game?

Problem #2

What is the perimeter of the orange triangle?

17 + 30.232 + 24.999 = 72.231 cm

Thanks for reading my Pythagoras Post (:
