Answer: The answer is (B) an enlargement with scale factor 2.
Step-by-step explanation: The quadrilateral K'L'M'N' is the dilation image of the quadrilateral KLMN. We are to select the correct description of the dilation from given four options.
We can record from the given graph that in quadrilateral KLMN, the length of one side is
KN = 1.5 units,
and in quadrilateral K'L'M'N', the length of the corresponding side is
K'N' = 3 units.
Therefore, the scale factor will be
So, there will be an enlargement with a scale factor 2.
Thus, (B) is the correct option.

Step-by-step explanation:
Triangle ABC ha vertices at: A(-3,6), B(0,-4) and (2,6).
Let us apply 90 degrees clockwise about the origin twice to obtain 180 degrees clockwise rotation.
We apply the 90 degrees clockwise rotation rule.
We apply the 90 degrees clockwise rotation rule again on the resulting points:
Let us now apply 90 degrees counterclockwise rotation about the origin twice to obtain 180 degrees counterclockwise rotation.
We apply the 90 degrees counterclockwise rotation rule.
We apply the 90 degrees counterclockwise rotation rule again on the resulting points:
We can see that A''(3,-6), B''(0,-4) and C''(-2,-6) is the same for both the 180 degrees clockwise and counterclockwise rotations.
A Major Arc within a circle is something that that is more than half of the circle, and therefore, larger than the minor arc. The way in which this could be used in an example is; Tony has a pizza with 8 slices, 6 of these slices are pepperoni and 2 are chilli beef. In this case, the pepperoni slices are the major arc and the chilli beef slices are the minor arc.
The Major Arc will always be bigger than the minor arc- whether this is 181 degrees to 179, or whether this is 350 degrees to 10 degrees.
The Minor Arc is always the smallest arc, and this can be explained by; Benedict has an apple pie that has 10 slices, between him and his friends, they have eaten four slices. In this case, they have eaten the 'minor arc'
There is a picture attached, and this is the examples of a major and a minor arc.

In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x. <u><em>Courtesy to Wikipedia</em></u>
