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 ![(x, y)\rightarrow (2x, y)](https://tex.z-dn.net/?f=%28x%2C%20y%29%5Crightarrow%20%282x%2C%20y%29)
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.
Ab means A multiplied by B.
Now, let's say Ab is 1*2
Then ba would be 2*1
So yes, they're technically the same. Just in a different order.
Answer:
1/4 + 1/4 + 1/4 or 1/8 +1/8 +1/8 +1/8 +1/8 +1/8
Step-by-step explanation:
To decompose a fraction simply means to take it apart. The most basic way to decompose a fraction is to break into unit fractions, which is when the numerator (top number) is 1. We can see that 6/8 is the same as the unit fraction 1/8 six times.
