The letter A labelled on the circle shows a _________.

This symbol is used to show a battery on electronics diagrams. One of the following statements is true about this symbol 

Identify the figure. 

Intersecting lines are those that meet each other at a certain point on the plane whereas perpendicular lines are those which meet each other at a 90° angle.
Since in the given diagram the 2 lines never meet each other, options b & c are eliminated and since the lines also appear to be equidistant from each other, option d is also eliminated.

Number of lines of symmetry does a rectangle have_________. 

When we fold the rectangle along its diagonals, we wouldn't get 2 equal parts as the adjacent sides in a rectangle are not equal.

Number of lines of symmetry does a number 8 have______ 

___________ lines of symmetry does a Taj Mahal have. 

On the figure shown, DC is a _______.

1. A Ray refers to that part of a line which has 1 end point and other end has no end i.e. it is infinitely increasing at one end.
2. A line is a geometric object (collection) with infinitely increasing ends i.e. it has no end on both sides.
3. Since the given figure is that of a closed object, none of its sides can have any infinite ends.

A scalene triangle has _________ lines of symmetry. 

Number of lines of symmetry in the figure given below is/are 

Hexagon has ___________ lines of symmetry. 

Square has _________ lines of symmetry. 

A part of a line; it has one endpoint and continues without end in one direction.

Note that a ray has one end point fixed and the other part is extending infinitely.

The following letter have no line of symmetry. 

Example of a shape has 3 lines of symmetry.  

An exact location in space.

Note that a point is dimensionless; it has only the position in space and gives an exact location in space.
