A plane shape, also known as a flat shape or a two-dimensional shape, is a geometric figure that exists in a plane. In mathematics, a plane refers to a flat surface that extends infinitely in all directions. Plane shapes are commonly studied in geometry.

Examples of plane shapes include:

1. Triangle: A triangle is a polygon with three sides and three angles. Triangles can be classified based on the lengths of their sides (equilateral, isosceles, or scalene) or based on the measures of their angles (acute, right, or obtuse).

2. Rectangle: A rectangle is a quadrilateral with four right angles. Its opposite sides are equal in length, and it has two pairs of parallel sides.

3. Circle: A circle is a perfectly round shape with all points on its boundary equidistant from the center. The distance from the center to any point on the circle is called the radius, and the distance across the circle passing through the center is called the diameter.

4. Square: A square is a quadrilateral with four equal sides and four right angles. It is a special type of rectangle and can be considered as a special case of a rhombus.

5. Pentagon: A pentagon is a polygon with five sides and five angles. The sum of angles in a pentagon is always 540 degrees.

6. Hexagon: A hexagon is a polygon with six sides and six angles. The sum of angles in a hexagon is always 720 degrees.

7. Trapezoid: A trapezoid, also known as a trapezium, is a quadrilateral with one pair of parallel sides. The other two sides are non-parallel.

These are just a few examples of plane shapes. There are many more, each with its own set of properties and characteristics. Understanding the properties and relationships of these shapes is important in various areas of mathematics and real-life applications.
