Do you know why these words are related to the artifacts? I DO ! The word legs relate to the right triangle because well you know the small square in the corner? That's the 90 degree angle. In other words its called 'A' and 'B' , which are the legs. If they can make a right triangle, they are called complimentary angles.
The word hypotenuse relate to side 'C' of the right triangle. Side 'C' is the longest side of the right triangle. It is always across from the 90 degree angle.
The next word R.A.T stands for Right Angle Triangle. It means that a triangle has a right angle (90 degree angle).
The word Greek relates to Pythagoras. Pythagoras was a greek person that was the father of math.
The first artifact is a triangle. This triangle is a R.A.T (right angle triangle) because it has a 90 degree angle. You can tell if its a right triangle because of the square at the corner. This right triangle has two sides that are the legs, which are 'a' and 'b'. It also has two angles which are theta and beta. These angles create a complimentary angle because together they create a 90 degree angle. The longest side of the triangle which is 'c' is called the hypotenuse.
The second artifact is a square. To be sure it is a square, we have to put lines on each four sides because that tells us that each side are equal and that it's a square. The four sides of the square are called lines of symmetry. This square has four right angled triangles at each corner. You can also get two right triangles from one square because if you cut the square in half, you get two right angled triangles. The whole square equals to 360 degrees (4 x 90 = 360).
The last artifact is a picture of Pythagoras. He was greek and a very intelligent mathematician. Pythagoras was known has the father of math. He was the one who created the Pythagorean Theorem, a² + b² = c². Pythagoras is a vegan (vegetarian), a person that doesn't eat a live things. He was the one who discovered the circumstanes-cosmos of the earth and that the sun goes around the earth. He was into harmonics which meant that he loved music. Pythagoras thought that he could make a square into four triangles and that he could make a triangle out of 3 squares.
In this problem that Mr.Harbeck gave us, we had to find the base of the triangle. This picture explains how I solved 'c'.
First, you need to find out how long each side of the square is. Then that will give you side "A" and "B" for the triangles since they're both the same length. Okay so, like a normal question find the length of the hypotenuse, which is 'c'. Once you have gott that you can now label the triangle and add up all the sides to find the perimeter.
The first thing I would do to be able to solve this equation is by isolating the variable which is "n". Second, you would have to add the opposite, which is -7 to +7. You then cancel them out because they are zero pairs. After you are left with "n". Third, you need to balance it out by doing the same thing to the other side. So it would be like this.. 10-7=3. Then your left with the answer of n=3. The last step is to verify (substitute) and that is very important! You first need to rewrite the equation. Then you replace the variable to the answer you got which is n=3. So it would look like this 3+7=10. Then you would write down 10=10 to finish it off. 
The first thing to do to solve this subtractive equation is to isolate the variable. Second, you add the opposite, which is +2 to -2. You then cancel them out because they are zero pairs. Third, you need to balance it out by doing the same to the other side. So you add +2 to the answer 14 and you solve it. Then you are left with n=16, which is the answer. The last and important step of all is to verify! You first need to rewrite the equation. Second, you replace the variable with the answer you got, which is n=16. So it would look like this... 16-2=14. The last step is to write down 14=14 to show that you are done.
The first step for solving a multiplicative equation is to isolate the variable. You then add the opposite and cancel it by dividing 3 to 3. So you are not left with "n". Third, you balance it out by doing the same thing to the other side. So you solve 12/3 which equals to 4 and the answer your left with is n=4. The last and important step is to verify! You first need to rewrite the equation. Then you replace the variable with the answer you got, which is n=3. So it would look like this....3(4)=12. The last step is to write 12=12 to show that you are done. 
The first thing you do to solve this equation is to isolate the variable. You then add the opposite by dividing 2 by 2. So now you are left with "n". Third, you balance it by doing the same thing to the other side. You multiply 5 by 2 and now your left with the answer 10. Now the last and important step of all is to verify! You first need to rewrite the equation. Second, you replace the variable with the answer you got, which is n=10. The last step is to write down 5=5 to show that you are now done.
