They are congruent shapes.
There is no specific name for them.
Then the two lines cut through by transversal line are parallel to each other.
Two angles are congruent if they have the same measure.
That is called a regular polygon.
are angels having not equal,zize shape and measurement
Neither. It forms 4 congruent angles and, as far as I am aware, no angels.
That is a mathematical impossibility. At least 2 angles have to be congruent in order for the shape to have 4 sides.
All 4 angles of a rectangle are congruent each measuring 90 degrees
I think it is a yes
A square has 4 congruent sides and 4 right angles
Not sure about angels, but if angles will satisfy you, the answer is a rectangle
It is a square
Circles, some triangles, and irregular polygons
