To determine whether a triangle with side lengths 6, 10, and 8 is a right triangle, you would use the Pythagorean theorem. A triangle is a right triangle if \( a^2 + b^2 = c^2 \), where \( c \) is the length of the longest side.
In this case:
- The sides are 6, 8, and 10. The longest side \( c \) is 10.
Now, you calculate:
- \( 6^2 + 8^2 \)
- \( 10^2 \)
Calculating these gives:
- \( 6^2 = 36 \)
- \( 8^2 = 64 \)
- \( 10^2 = 100 \)
Now sum \( 6^2 + 8^2 \):
- \( 36 + 64 = 100 \)
Since \( 100 = 100 \), this means that the triangle with sides 6, 8, and 10 does form a right triangle.
Elinor's calculations were incorrect. She mistakenly compared the squares while not setting the longest side correctly as \( c \). Hence, the correct response is:
No, she should've added \( 6^2 \) and \( 8^2 \) and compared that to \( 10^2 \).
