You could have a 3,4,5 right triangle (perimeter=12), or an equilateral triangle with each side = 4, then a square with each side = 3, a rectangle with length=5 & width=1, a pentagon with each side= 2.4, a hexagon with each side = 2, a decagon (10 sides) with each side= 1.2, a dodecagon (12 sides) with each side = 1. You could go on and on.
it means make same shapes only perimeter
Triangle square & rectangle
Yes - even shapes with different area.
You can't. Different shapes with the same perimeter may have different areas.
Most shapes have different perimeter than area, as far as value.
it means make same shapes only perimeter
yes they can
Any plane shape can have the same perimeter as any other plane shape.
Triangle square & rectangle
Congruent shapes are two shapes that are the same (angles, size perimeter/circumference)
Yes - even shapes with different area.
You can't. Different shapes with the same perimeter may have different areas.
Most shapes have different perimeter than area, as far as value.
Most shapes can have the same area and different perimeters. For example the right size square and circle will have the same are but they will have different perimeters. You can draw an infinite number of triangles with the same area but different perimeters. This is before we think about all the other shapes out there.
Only if they have the same number of sides.
Yes. Ex: A 5"x4" rectangle has the same perimeter as an equilateral triangle with sides 6" long.
There is no name for such shapes because "same size" is not defined. Does it mean same area? same perimeter? same major diagonal?
