Question

6. The point A(5, -1) on reflection in the x-axis is mapped onto A'. Also, A on reflection in the y-axis is mapped onto A". Write the distance between the images A' and A". ​

Answer 1

Answer:

The distance between the points is √85 cm.

Step-by-step explanation:

Given :  Point A(5,-1)

To find :  The distance between the points A¹ and A¹¹

Solution :

Reflection of the point (5,-1) in X-axis = (5,1)

Reflection of the point (5,-1) in Y-axis = (-5,-1)

Distance between two points A¹ and A¹¹

=√(-4-5)²+(-1-1)²

=√(-9)²+(-2)²

=√81+4

=√85 cm
