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! :)
