Questions & Step-by-Step Solutions
In triangle GHI, if GH = 8, HI = 6, and GI = 10, is triangle GHI a right triangle?
Step 1: Identify the lengths of the sides of triangle GHI. They are GH = 8, HI = 6, and GI = 10.
Step 2: Recall the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
Step 3: Identify the longest side, which is GI = 10. This will be our hypotenuse.
Step 4: Calculate the square of GH: 8² = 64.
Step 5: Calculate the square of HI: 6² = 36.
Step 6: Add the squares of GH and HI: 64 + 36 = 100.
Step 7: Calculate the square of GI: 10² = 100.
Step 8: Compare the results from Step 6 and Step 7. Since 100 = 100, the condition of the Pythagorean theorem is satisfied.
Step 9: Conclude that triangle GHI is a right triangle.
