Can the pythagorean theorem work for all types of triangles?

it works for only right angles. triangles.......

Right angled triangles only.

No, the Pythagorean Theorem just can work for RIGHT TRIANGLES (one angle is 90°).

it only works with right angled triangles

No, but the law of cosines is a generalization that does. Look it up on Wikipedia.

ya, any triangle having one angle atleast 90 degree.

The pythagorean theorem a^2 + b^2 = c^2 works only for right triangles with legs measuring a and b and a hypotenuse of length c.

only right triangles
