A Square
No shape can have two corners
triangle
rectangle
A trapezoid has exactly one pair of parallel sides
four sides and four corners
No shape can have two corners
No such shape exists.
There is no such shape. If it has two sides meeting, it also has to have a corner. A triangle has three sides and three corners, and a square has four sides and four corners. There is nothing in between.
triangle
The shape is a square.
A QUADRILATERAL has four corners and four sides, along with four angles. These do not need to be congruent (equal) but they can be.
cannot be a polygon.
A triangular based pyramid.
rectangle means that it is a 2D shape and it has four sides and four corners
rectangle
A trapezoid has exactly one pair of parallel sides
Both statements are not always true. A square is a rectangle (a shape four sides and four corners which are all right angles) but a rectangle is not necessarily a square (a shape with four equal sides and four corners that are all right angles).
