Question

Triangle CDE has side lengths of 24 cm, 16 cm, and 12 cm. Is triangle CDE a right triangle?

Answer 1

No,

Explanation:

For CDE to be a right triangle, a²+b²=c², where C is the hypotenuse. A and B are both legs or sides which make up the right triangle.

1. First, we plug in our side lengths for a, b, and c. We know that 24 would be the hypotenuse, since it is the longest side length. 16²+12² = 24²
2. The next step is to simplify the expression (exponents first!) 256+144=576
3. Then, we add like terms 400=576
4. Since 400 obviously does not equal 576, this triangle is NOT right

Answer 2

Explanation:

Yes it is.
