Question

plot the following points on your graph sheets: A (-4,0) B (-3,2) C (0,4) D (4,1) E (7,3). reflect the points B C D E on x axis and name them B' C' D' and E' respectively. Join the points ABCDEE'D'C'B' and A in order. NAME THE CLOSE FIGURE FORMED.

Answer 1

Answer:

A nonagon is formed by joining these points.

Step-by-step explanation:

The points to be plotted on graph are:

A (-4,0)

B (-3,2)

C (0,4)

D (4,1)

E (7,3)

The reflection of points on x axis B, C, D and E are B', C', D' and E' respectively are:

Method: We can simply revert the sign of y coordinate (If positive coordinate, make it negative and if negative coordinate, make it positive) of the points to get the reflection on x axis.

So, B' (-3,-2)

C' (0,-4)

D' (4,-1)

E' (7,-3)

Plotting all the points on graph and joining them in the following order:

ABCDEE'D'C'B'A

The closed figure formed is a nonagon (polygon having 9 sides).
