A square.
A pentagon maybe even A polygon
The figure that has 4 sides and 3 corners is a triangle-shaped figure that has one of its corners truncated or cut off. This figure is called a "truncated triangle" or a "triangle with a missing corner" and has a unique shape that can be used in geometric and mathematical applications.
A geometric figure with a polygonal base and triangular sides is called a pyramid.
A pentagon has 5 sides
inscribed angles
A square. Or a rectangle. A square.
A triangle is a geometric figure that is made of three line segments. It is a closed figure and has three angles.
A square.
A pentagon maybe even A polygon
paralellogram
A square is a plane geometric figure having 4 equal sides and 4 right angles.
Each side is called a face.
Quadrilateral is the name fr a geometric figure with 4 sides.
For a Polygon, "Poly" means "many" or "a number of"; "gon", roughly means "angles". So a poloygon is a figure with a number of angles between its sides. . If the number of sides is definite then "poly" is replaced by a word meaning that number.
A hexagon is any two-dimensional polygon with six sides and six vertices. If it is a regular hexagon, then opposite sides are parallel and each of the angles equals 120 degrees. The six interior angles then add up to 720 degrees
