Julio says that 6, 7, and 12 will make a right triangle but Matt says they will definitely not. Prove who is correct and show an example.
The Pythagoras theorem formula states that in a right triangle ABC, the square of the hypotenuse is equal to the sum of the square of the other two legs. If AB, BC, and AC are the sides of the triangle, then: BC2 = AB2 + AC2. While if a, b, and c are the sides of the triangle, then c2 = a2 + b2.
so if c² = a² + b²
12² = 6² + 7²
144 = 36 + 49
144 = 85
it is not a right triangle, so Matt is right

15 units²
Step-by-step explanation:
Hi there!
where <em>b</em> is the base and <em>h</em> is the height
Plug in the base (7.5) and height (4):
Therefore, the area of the triangle is 15 units².
I hope this helps!
