The equation for the Pythagorean theorem is. a 2 + b 2 = c 2. where a and b are the lengths of the two legs of the triangle, and c is the length of the hypotenuse. [How can I tell which side is the hypotenuse?]Pythagoras' Theorem works only for right-angled triangles. But we can also use it to find out whether other triangles are acute or obtuse, as follows. If the square of the longest side is less than the sum of the squares of the two shorter sides, the biggest angle is acute .
This is the Pythagorean Theorem with the vertical and horizontal differences between (x_1, y_1) and (x_2, y_2). Taking the square root of both sides will solve the right hand side for d, the distance.

Now triangle ACD is a right triangle. So by the statement of Pythagoras theorem, ⇒ AC2 = AD2 + CD2. ⇒ AC2 = 42 + 32. ⇒ AC2 = 25. ⇒ AC = √25 = 5. Therefore length of the diagonal of given rectangle is 5 cm. Example 3: The sides of a triangle are 5, 12, and 13. Check whether the given triangle is a right triangle or not.
Now I'll plug these into the Pythagorean Theorem, and solve for the length d of the wire diagonal: 5 2 + 8 2 = c2. 25 + 64 = 89 = c2. \small {c = \sqrt {89\,} \approx 9.43389} c= 89 ≈9.43389. So the bracing wire will be nine feet long, plus another 0.43389 feet or so. There are twelve inches in one foot, so:

About. Transcript. The Pythagorean theorem is a cornerstone of math that helps us find the missing side length of a right triangle. In a right triangle with sides A, B, and hypotenuse C, the theorem states that A² + B² = C². The hypotenuse is the longest side, opposite the right angle. Created by Sal Khan.
