Why does a square number always have an odd amount of factors?

let's ask a related question: why do number that aren't squares always have a even number of factors?

this answer is that the factors of a number comes in pairs. for example, the factors of the number 20 are: 1,2,4,5,10, and 20. Because you can write the number 20 as: 1 x 20, 2 x 10, or 4 x 5

for any number that is not a perfect square ever factor will have a partner that you multiply it by in order to get the number. therefore, each factor has a number and therefore the number of factors are always even.

for a perfect square there will always be a lone factor who doesn't have a partner. the question you have to answer is "why is that", to solve your math problem.

hope this helped the best I can do and it's the best way I know to explain it

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
