do you mean math equation? If you add a number to both sides of an equation you do not change it. That is called algebra
that all sides equal only 90 dreegers
Symmetry means that all sides of something is balanced. This is common in art and math.
Add up all the sides together
it is called a trapazoid. I asked my math teacher just for this reason!

Deca means ten. In math, a polygon called a decagon has ten sides.
"a shape with twelve sides is called a 12-gon..... i promise its in my math book!" Officially its called a dodecagon. Often polygons with a lot of sides start being called x-gon where x is the number of sides.
yeah there is. it has twenty eight sides. my teacher is part of some math committee where she gets all the latest math rules and stuff. she drew it on the board and it is really weird.
add the lengths of all the sides
the sum of all sides are called a perimeter
It means that all sides of the shape are equal.

No; that's perimeter, or the distance around.
Such a figure is called a square. Actually only one right angle is enough to force the the other angles to be right, and if three sides are equal, that forces all sides in such a figure to be equal. Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.
