Converse Pythagorean
1. The problem asks us to determine which three sticks form a right triangle. According to the Converse of the Pythagorean Theorem, if for three side lengths $a$, $b$, and $c$ (with $c$ the longest), $a^2 + b^2 = c^2$, then the triangle is right-angled.
2. Check each combination by ordering the sides and comparing sums of squares:
- Combination 1: $6$, $7$, $8$
- Longest side: $8$
- Check if $6^2 + 7^2 = 8^2$:
$$6^2 + 7^2 = 36 + 49 = 85$$
$$8^2 = 64$$
$85 \neq 64$, so no.
- Combination 2: $6$, $7$, $10$
- Longest side: $10$
- Check if $6^2 + 7^2 = 10^2$:
$$36 + 49 = 85$$
$$10^2 = 100$$
$85 \neq 100$, so no.
- Combination 3: $6$, $8$, $10$
- Longest side: $10$
- Check if $6^2 + 8^2 = 10^2$:
$$36 + 64 = 100$$
$$10^2 = 100$$
$100 = 100$, so this combination forms a right triangle.
- Combination 4: $7$, $8$, $10$
- Longest side: $10$
- Check if $7^2 + 8^2 = 10^2$:
$$49 + 64 = 113$$
$$10^2 = 100$$
$113 \neq 100$, so no.
3. Only the combination $6$, $8$, and $10$ satisfies the converse of the Pythagorean Theorem.
**Final answer:** Max should use the sticks of lengths 6, 8, and 10 inches to make a right triangle.
