The sequence of the transformations are reflection, then rotation, then translation.
<h3>What is reflectional symmetry?</h3>
Consider a plane. Consider a design or shape on that plane. Now consider an axis.
If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.
Triangle A B C is reflected across B C to form triangle A prime B C.
Triangle A prime B C is then rotated about point A to form A prime B prime C prime.
Triangle A prime B prime C prime is then shifted to the right to form A double-prime B double-prime C double-prime.
The sequence of three rigid transformations used to map TriangleABC onto TriangleA"B"C".
The transformations are reflection, then rotation, then translation.

1m=100cm
85 cm
400 mm=40 cm
Add up them up and you get 225 cm in total
When you multiply fractions, you multiply across, right? so, for example 5/7 times 4/9 will give you 20/63. So, if you do this to this problem, you will have abcd/bcde. but now you are able to cancel out the b and c and d. think of it like reducing. 5/10 is 1/2. Why? because if you reduce/factor out a 5, you get a 1 in the numerator and a 2 in the denominator. same thing here; you can factor out a b, c, and d(because they show up in both num. and denom. so what you are left with is a/e.
