Chapter SR16, Problem 11P

Solution

A line of symmetry for the figure is shown in red. Find the coordinate of point A.

A(-2, 2).

Given:

The given figure.

  

Concept Used:

• The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry.
• It is also termed as the axis of symmetry.
• The line symmetry is also called a mirror line because it presents two reflections of an image that coincide.

Calculation:

The given figure is -

  

The line of symmetry is passes at y=x.

So the coordinates of point A will be x=-2 and y=2

Coordinate of A(-2, 2).
