Question
The Pythagorean Theorem ONLY works on ______ triangle
- Obtuse
- Scalene
- Isosceles
- Right
Hint:
We are given a statement. We are asked to write the triangle for which Pythagoras theorem is used. Pythagoras theorem is means the square of the length of the hypotenuse is equal to sum of the square of the other two sides.
The correct answer is: Right
Pythagoras theorem is used for the triangles having one angle 90°.
The triangle which has one angle 90° is right-angled triangle.
So, Pythagoras theorem can be used only on right-angled triangles.
