Question

Polygon EFGH is a reflection of ABCD. Which of the following angle are congruent

Answer 1

Angle B and F, the second option

Answer 2

Answer:

B) ∠B and ∠F

Step-by-step explanation:

Here the polygon ABCD reflected over the y-axis and got the polygon EFGH.

When the polygons are reflected the measure of angles will not be changed and only the coordinates will be changed.

Here polygon ABCD is reflected over y-axis. So only the sign of the x -coordinate will change.

Let's see them.

A = (3, -1) ---> E = (-3, -1)

B = (5, -3) ---> F(-5, -3)

C = (4, -6) ----> G(-4, -6)

D = (1, -4) ----> H(-1, -4)

You can see the only x coordinate's sign changed.

Therefore, The ∠B and ∠F is true.
