Shapes

Let us see some of the basic shapes:

• A rectangle has 4 sides and 4 corners, opposite sides are equal.
• A triangle has 3 sides and 3 corners.
• A square has 4 sides and 4 corners. All the sides are equal.
• A circle and oval has no sides and corners.

Lines

Straight Lines

A line which is on a straight path without bending is called a straight line.

Example:

If we fold a paper, to get a crease, we get a straight line on unfolding the paper.

Curved Line:

A line which is continuously bending without causing any particular angle is called a curved line.

Example:

Children while playing hold the string loose in their hands, which forms a curved line.

Drawing Lines

Straight lines can be drawn using a scale or any straight edge like the edge of a notebook or pencil box.

Drawing a straight line:

1. Using a scale:
2. Using a pencil box
3. Using a notebook

We keep the scale in the following positions for drawing the following lines.

Solid Figures (3-D Shapes)

The shapes we have seen so far are,
Square, triangle, rectangle, oval which are all flat shapes without any thickness.
But there are many objects which are not flat, like a ball, a dice, a pencil box, a party hat, a gas cylinder etc.
These are called "solid shapes".
There sides or faces may look like flat shapes, such as square, triangle or a circle.
Examples:

Faces, Edges And Corners

Faces: The outside of a solid is called its face.
Edge: Two faces meet to make an edge.
Corner: The place where two sides meet is called a corner.
Examples:

Let us consider a table for better understanding of the shape, edges and corners/vertices of various objects.

Tracing Out Flat Shapes

A few flat shapes that we have learnt about can be drawn with the help of solid shapes.
We can trace the base of a solid shape to get a flat shape.

Examples:

1. The base of a dice which has shape of a cube, a square can be traced.
2. The base of a pencil box which has shape of a cuboid, a rectangle can be traced.
3. The base of a cylinder which has a curved shape, a circle can be traced.

The sides or faces of many objects we see are like flat shapes we earlier noticed.
