Question

Identify the symmetrical instruments from your mathematical instrument box.

Answer 1

Hint: Before solving this question, we must know the meaning of symmetry.
Something is symmetrical when it is the same on both the sides. A shape has symmetry if a central dividing line can be drawn on it, to show that both sides of the shape are exactly the same (just like a mirror image). A line of symmetry divides any shape or object into identical parts.

For example:-

Complete step-by-step answer:
The symmetrical instruments from mathematical instrument box also called the geometry box are as follows:
A Pencil
An Eraser
A Ruler or Scale
A Protractor
A Divider
They all are symmetrical, which means that they are the same on both the sides.

Note: It is not always necessary that a shape or an object will always have just a line of symmetry. In other words, a shape or an object can have more than just one line of symmetry. For example, a circle does not have only one line of symmetry.
A circle has infinite lines of symmetry. This means that a circle has infinite lines of symmetry. Likewise, a triangle has three lines of symmetry, while rectangle and square have four such lines which divide them into identical parts.
