The reflection shown in the picture is an example of what's called a <em>rigid transformation</em>, one that doesn't deform the original shape in any way. Rigid transformations preserve lengths and angles, which means that the measure of some angle ∠A is going to be equivalent to the measure of the corresponding transformed angle ∠A'
Here, we see that the only response which represents that correspondence is the last one: m∠BCA = m∠B'C'A'

Step-by-step explanation:
Area of Circle having radius OP = 4 cm: 50.27 cm²
Area of Circle having radius AD = 1 cm: 3.14 cm²
Area of Circle having radius BC = 2 cm: 12.57 cm²
Area of the shaded region: 34.56 cm²
Circumference of the circle with center B: 12.57 cm
<h3>Area and Circumference of a Circle</h3>
Area = πr²
Circumference = 2πr, where r = radius.
Area of Circle having radius OP = 4 cm:
Area = π(4)² = 50.27 cm²
Area of Circle having radius AD = 1 cm:
Area = π(1)² = 3.14 cm²
Area of Circle having radius BC = 2 cm:
Area = π(2)² = 12.57 cm²
Area of the shaded region:
Area = 50.27 - (3.14 + 12.57)
Area = 34.56 cm²
Circumference of the circle with center B, having radius of 2 cm:
Circumference = 2π(2) = 12.57 cm
