What are Geometric Shapes?
An enclosed figure made by joining two or more points, lines, or curves is known as a geometric figure. For example, a triangle made by joining three lines is a geometric shape. Similarly, a circle is a geometric shape, made using a curve. Both the examples discussed above are 2D geometric shapes.
Types of Geometric Shapes
Based on the dimensional properties, geometric shapes can be classified into 2D Geometric Shapes and 3D Geometric Shapes. Let us understand them in detail along with the list of geometric shapes and their properties.
2D Geometric Shapes
2D meaning two dimensional refers to figures that have only one plane/surface. The figures that have only two dimensions (length and breadth) are called 2D geometric shapes. In simple terms, the figures that can only be drawn on to a plane surface (like paper) are 2D figures.
What is the name of the letter that represents the various sizes of an object?
Size dimension – The dimensions which indicate the various sizes of the object such as length, breadth, diameter etc. are known as size dimensions. These dimensions are represented by letter ‘S’.
What is the plane that is horizontal and at right angle to the V.P?
1) Vertical plane: – The plane which is vertical is called vertical plane and is denoted by V.P. Vertical plane is also known as Frontal Plane as front view is projected on this plane. 2) Horizontal plane:-The plane which is horizontal and at right angle to the V.P is called Horizontal Plane and it is denoted by H.P.
How to avoid dimensioning to hidden lines?
1) Every dimension must be given, but no single dimension should be repeated. 2) Dimensions should be placed outside the views. 3) Avoid dimensioning to hidden lines wherever possible. 4) Dimension lines should not cross any other line of the drawing. 5) Aligned system of dimensioning is recommended.
What is parallelogram in math?
