The Pythagorean theorem holds true for which type of triangle?
- A.
All triangles
- B.
Right angled triangle
- C.
Isosceles triangle
Correct Answer
B. Right angled triangleExplanation
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem does not hold true for all triangles, as it specifically applies to right-angled triangles. In an isosceles triangle, two sides are equal in length, but the theorem does not apply unless the triangle is also right-angled. Therefore, the correct answer is "Right angled triangle."Rate this question:

True
- B.
False
Correct Answer
A. TrueExplanation
