Answer:
A. <em>ΔJKL is not congruent to ΔJ'K'L' because the rules do not represent a sequence of rigid motions.</em>
Step-by-step explanation:
ΔJKL is mapped to ΔJ'K'L' using the rules followed by
From geometry we know while rotating, reflecting and translating the size of the figure remains as it is, so they are congruent.
But in case of dilation the figure gets resized i.e their size gets changed. So they are similar not congruent.
In this case, first the triangle goes under i.e 2 units translated to right and 3 units translated to up.
But after then it undergoes , where it undergoes a dilation of factor 2, so it is no more congruent to the original figure.

The ratio between two numbers x and y is defined as x/y. It measures how many times y is contained in x. For example 12/8 = 1.5 means 12 is 1.5 times 8.
We have two key sets of data: the ratio between the surface areas of the cylinders and the fact that the radius and heights of the cylinders come in the same proportion.
First, we can easily compute the ratio of the surface areas
It gives us the relation
Computing the square root
Computing the cube
