A square is a four-sided polygon, also known as a quadrilateral, where all four sides are of equal length. Each of the four interior angles of a square measures 90 degrees, making it a type of rectangle with equal sides. A square has two pairs of parallel sides and four right angles, making it a regular quadrilateral. It can also be seen as a rhombus with right angles or a rectangle with equal sides.

A triangle is a three-sided polygon with three edges and three vertices. The sum of the interior angles of a triangle always equals 180 degrees. Triangles can be classified based on their sides: equilateral (all sides are equal), isosceles (two sides are equal), and scalene (all sides are different). They can also be classified by their angles: acute (all angles less than 90 degrees), right (one angle exactly 90 degrees), and obtuse (one angle greater than 90 degrees). Triangles are one of the

 A circle is a round, two-dimensional shape where all points are equidistant from a central point called the center. The distance from the center to any point on the circle is called the radius. The longest distance across the circle, passing through the center, is called the diameter, which is twice the length of the radius. The boundary of the circle is called the circumference. Circles have no corners or edges and are symmetrical around their center.

 A rectangle is a four-sided polygon, also known as a quadrilateral, where opposite sides are equal in length and each of the four interior angles is 90 degrees. This means a rectangle has two pairs of parallel sides and four right angles. The longer sides are called the length, and the shorter sides are called the width. Rectangles are a type of parallelogram and are often seen in everyday objects and shapes, such as books, screens, and tables.

 An ellipse is a smooth, oval-shaped curve that looks like a stretched circle. It has two focal points, and the sum of the distances from any point on the ellipse to these two foci is constant. The longest diameter of the ellipse is called the major axis, and the shortest diameter is called the minor axis. Ellipses are symmetrical around both their major and minor axes and are commonly seen in planetary orbits and certain types of lenses.

 A trapezoid is a four-sided polygon, also known as a quadrilateral, w at least one pair of parallel sides. The parallel sides are called the bases, and the non-parallel sides are called the legs. The height of a trapezoid is the perpendicular distance between the bases. Trapezoids can have various angles and side lengths, but the defining characteristic is the single pair of parallel sides.
