Check the picture:
Rotating JKL 180° with respect to the origin, and translating it 1 unit up, we get J'K'L'.
That is, the 2 triangles match perfectly.
Answer:
<span>△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a rotation of 180° about the origin followed by a translation 1 unit up, which is a sequence of rigid motions.</span>

Answer:
Therefore,
Probability for getting a number less than 4 is
Step-by-step explanation:
Given:
Let the Experiment be of rolling a 6 sided,
Let the sample space of the above experiment be S,
S = { 1, 2, 3, 4, 5, 6 }
n(S) = 6
Let A be the event of getting a number less than 4,
A = { 1 , 2, 3, }
n(A) = 3
Then the probability for getting a number less than 4 is given by.
Substituting the values we get
Therefore,
Probability for getting a number less than 4 is
The ratios are not equivalent.
Basically substitute y into the first equation: 2x+8(2)=20 and solve. Then plug in x to the second equation etc.
