In order to calculate either of the two legs or the hypotenuse of a Right Triangle, you will need to use the Pythagorean Theorem.
Pythagorean Theorem: A2 + B2 = C2
If you're working with a value that is already squared, then you'll need to square it again, in order to make the Pythagorean Theorem work.
Equation: (A2) + [(x2)2] = (C2) {Note: B = (x2)}
When simplified: (A2) + (x4) = (C2)
Suppose you have one leg with a length of 3 and a hypotenuse with a length of 5. Your remaining leg has a length of x2.
If you plug these numbers into the Pythagorean Theorem, you'll notice an equation like this:
32 + (x2)2 = 52 {Note: x2 = B}
Simplified:
9 + x4 = 25
[(9 + x4) - 9] = (25 - 9)
x4 = 16
{Note: sqrt means Square Root}
[sqrt(sqrt(x4))] = sqrt(sqrt(16))
x = sqrt(sqrt(16)) = 2
In other words, the square root of the square root of 16, equals 2. So, if the square of 2 is 4, then the square of 4 is 16.
Therefore, 32 + (22)2 = 52
OR
9 + (2*2)(2*2) = 25
OR
9 + 4*4 = 25
OR
9 + 16 = 25 {<- This is your answer to the Pythagorean Theorem}
OR
[(9 + 16) - 9] = (25 - 9)
OR
16 = 16 {proof your calculations are correct}
Form a right angle triangle under the slope and divide the base of the triangle into the height of the triangle.
Yes.
A square.
Put the two bases of the triangle together. To form a square. Place the squares side by side to form a rectangle
A right angle isosceles triangle is then formed which will have two 45 degrees angles and one 90 degrees angle.
I think that this is right: if you double the triangle, to form a square and you have the height, then the height shoulc be one side of the square. As it is a square, then the base should be the height, but it will only work if it is an equilateral triangle and all of the sides are the same. good luck, and I do apologize if I am wrong!!!! :)
Measurement comparisons. The square, right triangle, equilateral triangle and the circle are represented in the human form.
Use Pythagoras. The diagonal, and two sides of the square form a right angled triangle. So if each side of the square is x cm long, the diagonal is x*sqrt(2) cm long.
Form a right angle triangle under the slope and divide the base of the triangle into the height of the triangle.
Yes.
Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.
They are the "legs" of the triangle.

Yes. The square is a special form of the angle notation, which specifies a right angle. It is common to put it there, since it clearly defines that triangle as a right-angled and not just a very close one.
Well, in order for a shape to be a triangle, it can only have one right angle. Therefore, it is called a right triangle.
