Isometric shape
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.
Well, darling, to find the area of a shape, you need to know the shape itself! If those numbers represent the sides of a rectangle, you can pair them up to find the length and width. Then, just multiply the length by the width to get the area. So, in this case, the area would be 36 square centimeters.
A four-sided shape with only 2 sides the same length is called a rhombus.

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.
