Answer:
The triangle ABC is not a right triangle
Step-by-step explanation:
For a right angle triangle, we have;
The square of the longest side or leg of the triangle is equal to the sum of the squares of the other two legs
The parameters given from the question, are;
The square of of the length of side A = 7 inch²
The square of of the length of side B = 18 inch²
The square of of the length of side C = 27 inch²
Therefore, the the longest side is side C and the inch² sum of the squares of the other two sides are 7 + 18 = 25 inch² which is less than the square of the length of side C = 27 inch², therefore, the triangle ABC is not a right triangle.
