No. The Pythagorean theorem applies only to right triangles...those containing a right angle (90 degrees).
The Pythagorean Theorem is a statement about triangles containing a right angle. The Pythagorean Theorem states that:"The area of the square built upon the hypotenuse of a right triangle is equal to the sum of the areas of the squares upon the remaining sides."
With A=5 B=2 C=7, you don't have a right-angled triangle (90° angle), that's why you get a wrong answer. The Pythagorean theorem isn't wrong, YOU are wrong!
The Pythagorean theorem uses the right triangle.
Pythagoras' theorem is applicable to any right angle triangle and states that when its hypotenuse is squared it is equal to the sum of its squared sides.
it showed us how to determine the hypotenuse of right angle triangles
The Pythagorean theorem is actually the law of cos, where the angle is 90.
With right angle triangles
The Pythagorean Theorem states that in a right triangle with legs a and b and hypotenuse c, a2 + b2 = c2. The converse of the Pythagorean theorem states that, if in a triangle with sides a, b, c, a2 + b2 = c2 then the triangle is right and the angle opposite side c is a right angle.
With any right angle triangle
A right angle triangle.
The Pythagorean Theorem allows the mathematician to determine the value of the hypotenuse. The converse of the Pythagorean Theorem manipulates the formula so that the mathematician can use the values to determine that if the triangle is a right triangle.
No. The Pythagorean theorem applies only to right triangles...those containing a right angle (90 degrees).
Right-Angle triangles
Right angle triangles
When working out the sides of a right angle triangle.
Simply because the Pythagorean Theorem is not true for any triangle that doesn't have a right angle in it. If a triangle has a right angle in it, then it satisfies the Theorem. If it hasn't, then it doesn't. And if it satisfies the Theorem, then it has a right angle in it, and if it doesn't, then it hasn't.
