If you recall your multiplication tables, you can tell at first glance that 5, 10, and 12 do not define a right triangle.
.
We have the Pythagorean Theorem to guide us in solving right triangles.
c^2 = a^2 + b^2, where c = hypotenuse
.
5^2 = 25
10^2 = 100
12^2 = 144
.
144 is not equal to 100 + 25
.
There are several right triangles worth remembering.
1, 1, sqrt(2) is an isosceles triangle
1, sqrt(3), 2 is a 30-60-90 triangle
3, 4, 5 is a classic that is often used in carpentry
5, 12, 13 is good to remember, too
.
done.
