Well the remainder more possible dividing by six would be 9.3 I hope i helped.
There are 3 sides. If you draw out a triangle, each line is a separate side (a line segment connecting 2 vertices, or points). You can also see in the word "triangle" the prefix "tri-", meaning "three". It refers to the shape having 3 angles, but when there are 3 angles there are 3 sides to make it up. This is true for other shapes too - in a square, there are 4 sides connecting 4 points, and between each side is an angle, creating 4 angles.
You multiply it together like (a+b)(a+b)
the answer would be a^2 + 2ab + b^2
