Answer to Problem 2.7.5EP
The co-ordinates of the vertices of the triangle ABC when reflected about y axis is
Explanation of Solution
Given information:
The triangle is mentioned above in the problem.
Formula used:
On reflection about y axis the sign of x co-ordinate which of vertices of triangle ABC will change only that co-ordinate which lie on the negative of x axis.
Calculation:
Consider the triangle as mentioned above.
The vertices of triangle is mentioned below.
Recall that on reflection about y axis the sign of x co-ordinate which of vertices of triangle ABC will change only that co-ordinate which lie on the negative of x axis.
Therefore the calculation of co-ordinates are as follows.
Therefore the co-ordinates of the vertices of the triangle ABC when reflected about y axis is
