*supposedly*slipped on some ice, fell and

*bumped*his head which caused him to forget what he was going to teach us. To help him regain his memory, we were assigned:

- To explain the four artifacts
- How These Words Relate:
, and*Legs, hypotenuse, R.A.T., Greek*.*theorem*

Artifact #1:

The first artifact is known as a right triangle or a ** R.A.T. **(right angle triangle). What makes this triangle a R.A.T. / right triangle,

*is the 90° right angle where the square on the bottom left corner is placed. The two sides that create this right angle are called*

*legs.*The

*other two angles are called*

*theta*and

*beta,*together they equal to 90°, which makes them

*complementary angles*. The longest side of the triangle or the side across from the right angle, is known as the

*hypotenuse.*The hypotenuse is usually labelled as "C" and the legs are labelled as "A" and "B".

Artifact #2:

The second artifact is a square. The lines on each side of the square, are called

*lines of symmetry.*This shows all the sides are equal to each other, making it a square and

**not**a rectangle. In each of the four corners, are 90° right angles. Together, the whole square is 360° (4 x 90° = 360°). If you were to cut this square diagonally in half, you'd have two right triangles, like in the first artifact.

Artifact #3:

Who is this a sculpture of? Well he is a

**man of brilliance. He is thought to be the 'Father of Math'. This man's name is Pythagoras and was a vegan (someone whom doesn't consume any animal products). He was a mathematician who loved music. Pythagoras was the first to figure out the circumference of the earth and proved that the earth revolves around the sun. He was very fluent in Egyptian and was interested in harmonics. He also invented the Pythagorean**

*Greek***a² + b² = c².**

*Theorem,*The Pythagorean

*is a formula or theory that can be proved. This theorem finds out the length of the side 'C' on a right triangle. To figure out the length of 'C', you need to know what sides 'A' and 'B' are. Next, you square 'A' and 'B' and add them together, this will leave you with 'C²'. Last but not least, you must find the square root of the number and that gives you the length of 'C'.*
