Do 9, 12, 14 form a right triangle

defon

Answer:

Step-by-step explanation:

To determine if the 3 sides form a right triangle.

Use the converse theorem of Pythagoras.

If the square of the longest side is equal to the sum of the squares of the other two sides then the triangle is right,

longest side = 14 and 14 ² = 196

9² + 12² = 81 + 144 = 225

Since 196 ≠ 225 the triangle is not right

Pls help???? b isn’t right

spayn [35]

The correct answer would be A

Take the left triangle, flip it and put it on the right side. This should resemble a rectangle. Then calculate
