squares
A rectangular shape has a long side (length) and a breadth (width, short side). A square still has a length and width, though both are the same measurement to form a square.
Rectangle
An equilateral triangle; the sides are the same length and angle so its the same irrespective of how you tilt it.
calculate the length of each side then add them all up same with any 2d shape
squares
No. The sides of a shape don't need to be equal in length to be parallel.
a square
the shape is a regular shape if it has all the same angles and side lengths.
That would be an isosceles triangle.
If every side is the same length, then it's a rhombus.
If a triangle does not have the same length side as another triangle the sides are not congruent.
a rectangle. it has four parallel sides each side is the same length as the one on the other side.
Congruent Triangles have the same angles and side length measures
