a^2 +  b^2  =  C^2

12^2  -  9^2  =  A^2

225 - 81 = 144

Which transformation will carry pentagon EFGHI onto itself?
wariber [46]

Answer:

D

Step-by-step explanation:

The pentagon has 5 interior angles that add up to 360. To find the angle of rotational symmetry, divide 360 by 5 (you get 72). So if you rotated the shape 72 degrees, it will map onto itself. 72 times 2 is 144, and that's rotating the shape 72 degrees twice, so it will stay the same.
