A closed two-dimensional, or flat, figure is called a plane shape. Different plane shapes have different attributes, such as the number of sides or corners (or vertices). A side is a straight line that makes part of the shape, and a corner, or vertex, is where two sides meet.

What does plane shape mean?
A plane shape is a two-dimensional closed figure that has no thickness. A plane in geometry is a flat surface that extends into infinity in all directions. It has infinite width and length, zero thickness, and zero curvature.
What is plane shape example?
Some examples of plane shapes that you may see every day are stop signs, a sheet of paper, a paper plate, a stamp, or even a tortilla chip. There are many kinds of plane shapes, but we will focus on 5 basic kinds: squares, rectangles, circles, triangles, and octagons.
What is plane shape and solid shape?
The plane shapes are two-dimensional closed shapes with no thickness and are known as 2−D shapes. Solid shapes are nothing but solids with three dimensions: length, breadth, and height. Solid shapes are also known as 3−D shapes.
How do you identify a plane in geometry?
In a Euclidean space of any number of dimensions, a plane is uniquely determined by any of the following:
- Three non-collinear points (points not on a single line).
- A line and a point not on that line.
- Two distinct but intersecting lines.
- Two distinct but parallel lines.
Why a circle is a plane figure?
A circle is a plane closed figure enclosed by a curve, having no sides and no corner (vertex). Every point in the curve is situated at equal distance from a definite point within the closed figure. It has a point O within it from which the closing curve is equidistant to every point on the circle.
What is the plane of a triangle?
A plane is a flat or level surface in two dimensions. Figures such as circles or squares have all of their parts lying on a plane and thus, are examples of plane figures. A triangle is a closed plane figure bounded by three line segments.
What is a plane figure in mathematics?
A plane figure is a geometric figure that has no thickness. It lies entirely in one plane. Below are examples of different types of plane figures. A plane figure can be composed of line segments, curves, or a combination of the two. Plane figures are often categorized as open or closed.
What are plane and solid figures?
Answer: A plane figure is two-dimensional, and a solid figure is three-dimensional. The difference between plane and solid figures is in their dimensions. The same shape takes on extra dimension by adding additional points and lines to give the shape height, width and depth.
What are the properties of a plane shapes?
A plane shape is a geometrical form such that the straight line that joins any two points on it wholly lies on the surface. Examples of plane shapes are triangles, quadrilaterals, circle and other polygons. Properties of equilateral triangle:
- All sides are equal.
- All angles are equal.
- It has three lines of symmetry.
