Question

The subtraction symbol $ \left( - \right) $ has .......... lines of symmetry.

Answer 1

Hint: Symmetry means shape should look exactly like the other shape when the object is moved, rotated and flipped. For subtraction symbols if we cut vertically into two halves both look similar and now rotate it then cut the symbol horizontally then also the line is symmetric. Hence, the subtraction symbol has one horizontal and vertical symmetry.

Complete step-by-step answer:
The subtraction symbol $ \left( - \right) $ .
Symmetry is nothing but balanced and similar which can be found in two halves of the symbol.
The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called line of symmetry. Symmetry is used to describe that one shape looks exactly like the other shape when the object is moved, rotated or flipped.
The subtraction symbol divided in the half then both sides are equal. If we rotate the subtraction symbol by $ 90^\circ $ and divide it to two halves then it will also be symmetry.
Hence, there are two symmetric ones that are horizontal and vertical.
The subtraction symbol $ \left( - \right) $ has two lines of symmetry.

Note: Symmetry may be viewed when you flip, slide or turn an object. There are two types of symmetry which are Reflexive as well as Rotational symmetry. The concept of symmetry widely is used in geometry.
