Which polygons are congruent?

select each correct answer.

B and D.

Step-by-step explanation:

We know that the two polygons are said to be congruent if their corresponding angles and sides are equal.

A. The corresponding sides are not equal, therefore, the polygons are not congruent.

B. The corresponding sides and angles are shown equal, therefore, the polygons are congruent.

C. The corresponding sides are not equal, therefore, the polygons are not congruent.

D. The corresponding sides and angles are shown equal, therefore, the polygons are congruent.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

ratio is 2 : 9

the answer is three

13.5 : 3
