I don't know if there's a specific name for these two shapes, but the only two shapes that have 4 equal sides are the square and rhombus. The difference between the two is the square has 4 equal angles (90 degrees) and a rhombus does not.

Well if two triangles have sides of the same length, then by SSS they are congruent. In addition, if they have sides of the same length, their perimeters would be the same. So at first it seems like the answer would be yes. However, if is easy to come up with two triangles with the same perimeter whose sides do not have the same length Triangle 1 has sides 10, 15 and 30 to know if this is a triangle, we need the length of any side to be less the sum of the other two sides. So 10
To be called a square, a figure must not only have 4 sides, but also some additional properties. Specifically, in a square:All 4 sides have the same length.All angles are right angles.
The perimeter is the sum of all four sides; in a square, all four sides have the same length. Therefore, you simply need to divide the perimeter by 4.
a rectangle has four right angles and opposite sides are all the same length This means that a parallelogram is not always a rectangle, but a rectangle is always a parallelogram, by definition.
A four-sided shape with only 2 sides the same length is called a rhombus.

A shape with opposite sides parallel and of the same length and four right angles is a rectangle.
The shape is a square.

Oh, dude, that's an easy one. So, like, the shape you're describing is a square. It's got those four right angles and four sides that are all equal. It's like the basic bro of shapes, simple but classic.

A four sided figure with all sides the same length and opposite sides parallel.
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
