true
Yes, they could.
No, it is not. For a right triangle, from the Pythagoraen theorem, 7 squared plus 9 squared does not equal 12 squared
No they could not.
Yes.
Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.
i its isosceles
9 + (9 / 9) + (9 / 9) + (9 / 9) = 12
No because they don't comply with Pythagoras' theorem for a right angle triangle
Can 9, 8, and 17 for a triangle?
No. If they did, then A2 + B2 = C2. Try this using 7, 9, and 12: 72 = 49. 92 = 81. 49 + 81 = 130. But 122 = 144, which is not equal to 130, so these can't be the sides of a right triangle.
if it makes a right angled triangle then c squared = a squared + b squared 12^2 = 7^2 + 9^2 144 = 49 + 81 but 144 doesn't equal 130 so no it doesn't make a right angle triangle
9 and 7/12
