Solid geometry involves all the three dimensional shapes and their properties also.Two locate three dimensional shapes in geometry we use three dimensional coordinate system i.e.with their properties such as surface area, volume etc. Solid geometry involves all the three dimensional shapes like cube, sphere, cylinder, cone, prism etc.Two dimensional object does not possess faces and edges, they have only sides and vertices.Polygon and their types also involves in plane geometry.The shapes in two dimensions has only sides, perimeter and area.Plane geometry involves types of lines, types of angles, types of triangles and their properties.We can define or locate all two dimensional shapes in XY-plane.We can locate the two dimensional shapes in two dimensional coordinate system in XY-plane.Also, it includes perimeter, area of these shapes also.The two dimensional shapes are square, rectangle, triangle, circle etc.Plane geometry involves the shapes or objects which are two dimensional.While solid can be represented in three dimensional coordinate system only.

We can represents point, line and plane in two dimensional coordinate system. Now we see in detailed about plane geometry and solid geometry.

Finally, solid means a three dimensional shapes which is having 3 coordinates.

Plane is the two dimensional shape having two coordinates.

Line is the one dimensional shape which is locus of points along straight path.

A point is having no dimension and it has only its position.

Point, line, plane and solid are the basics shapes of geometry.

The mainly geometry can be studied in two parts, plane geometry and solid geometry.īefore going to learn about plane and solid geometry we see some basic shapes of geometry. It involves all shapes, their properties, solids, perimeter, area, volume, surface area of solid surfaces and shapes, coordinate system and all theorems based on it. For example,įor example, a square has 4 lines of symmetry, as shown below.We are not only learning the geometry but also playing with geometry from our childhood. Lines of symmetry in different symmetrical shapesĮach shape has a different number of lines of symmetry, whether it’s a quadrilateral rhombus or parallelogram, a scalene triangle or isosceles triangle, your child should understand that each shape has different lines of symmetry. However, shapes and objects that do not have two identical halves when divided with a line of symmetry are called asymmetrical figures.

If you were to place a mirror along this line, the shape would remain unchanged. In symmetrical shapes, like a regular polygon, this means that if you were to fold the shape along the line of symmetry, both halves would match exactly and be mirror images of each other. What is a line of symmetry?Ī line of symmetry is a line that cuts a shape exactly in half. But can be used for children of primary school age at any point of their journey into symmetry and mathematics.

This blog is part of our series of blogs designed for parents, teachers and carers supporting home learning and looking for home learning resources during the Covid-19 epidemic and beyond. To help your child understand this part of the maths curriculum, this guide helps explain what a line of symmetry is and provides a few practice questions to test their skills.
