__Pythagoras__

Pythagoras was a Greek mathematician, teacher and philosopher. He had his own theory which was obviously called the "Pythagoras Theory."

__Right Angle Triangle.__

A right angle triangle has one 90 degree angle. On the second picture you see the symbols Q and B. The Q is called theta, and the B is called beta. The symbol is there because it means that the angle degree is going to equal to 90 when you have two of it. But the two angles don't have to equal the same they could be different as long as the angles equal 90 degrees. The letter A and the purple B are called the legs. The purple C is the hypotenuse. The hypotenuse is the longest side of a triangle.

__Squares and Rectangles__

The picture above is a square and a rectangle. The lines on the square means that the dimensions are all equal. The lines in the rectangle have two ticks, and the other two sides have only one. That means that the two parallel sides are the same.

__Pythagoras Theorem__

The picture above is an example on how the problem looks like.

__Problem 1__

a² + b² = c²

you have to replace the letters into numbers

8² + b² = 10²

now we have to figure out what b equals

b²=(10x10)-(8x8)

b²=100-64

b²=36

we now have to find the square root of 36

b=6

you think we are finished but we aren't because there was two triangles. We now have to add 6+6. It equals 12 so b equals 12. Also don't forget the meter value.

b=12mm
