Solve the triangle: a = 10, b = 10, c = 15. if it is not possible, say so

Using the Theorem of Pythagoras (a² + b² = c²)

Put in the values:

10² + 10² = 15²
Is it correct? (solve)

Nope! Because 10² + 10² = 200, and the square root of 200 is about 14, not 15.

The answer is no, the side lengths 10, 10, and 15 cannot form a triangle.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
