I'm pretty sure you can use the Pythagorean Triples
Have you ever heard of a three four five triangle? sorry I don't think that was much help but rather a hint
which set of measures could be side lengths of a triangle?
a. 4 in., 9 in., 12 in
b. 3 cm.,6 cm, 9 cm
c. 4 mm, 12, mm, 20 mm
d. 5 ft, 6 ft, 13 ft
i don't know how to get the answer so can u please explain?
5 answers
no i haven't i;m only in 6th grade so can you break it down as easily as possible
A "Pythagorean Triple" is a set of positive integers, a, b and c that fits the rule:
a2 + b2 = c2
Example: The smallest Pythagorean Triple is 3, 4 and 5.
Let's check it:
32 + 42 = 52
Calculating this becomes:
9 + 16 = 25
And that is true
a2 + b2 = c2

However here
the sum of any two must not be less than the third side or they will not reach
b fails
c fails
d fails
ONLY A passes :)
