Answer:

The two given triangles ABC and A'B'C' are congruent by SSS or AA axiom of congruence.

Step-by-step explanation:

Rigid Transformation is a transformation which PRESERVES (keeps it SAME) the LENGTH and the ANGLES in an image and pre- image.

Here, as we can ΔABC goes under Rigid Transformation in to the ΔA'B'C'

⇒Sides AB, BC and AC correspond to the sides A'B',B'C' and A'C' respectively.

Also the ∠A, ∠B and∠C correspond to ∠A', ∠B' and∠C' respectively.

Now, in ΔABC and ΔA'B'C

AB = A'B'

BC = B' C'

AC = A'C'

⇒The two given triangles are congruent by SIDE SIDE SIDE property.

Also, ∠A = ∠A'

∠B = ∠B'

⇒The two given triangles are congruent by ANGLE ANGLE property.

Hence the two given triangles ABC and A'B'C' are congruent by SSS or AA axiom of congruence.

Your answers for the row #6 are (going from left to right) 7, 8, 9, 10, 11, 12

Step-by-step explanation:

Explanation-If you look at each column, you can see that if you take the top number on any row by its side number, you just add the two.

Take the number one on the left side and add it to the number one on the top column. 1 + 1=2. So therefore, that is why there is a 2 in the answer box. 1 + 2=3, which is the next answer. It's like a pattern. Just take the number on the side and add it to the top letter until you get to the end of the row.

Example- In the first row, it goes 1, 2, 3, 4, 5, 6, 7 for a reason. The reason you have 2 for the first orange box is because 1 + 1 = 2
