Answer:
2 and 6, 4 and 8, 1 and 5, 3 and 7
Step-by-step explanation:
The angle rule of corresponding angles states that the corresponding angles are equal if a transversal cuts two parallel lines.
In this example, lines m and l are two parallel lines
line n cuts through both, making every other angle corresponding and congruent, etc...

----> 
see the attached figure to better understand the problem
Triangles ABD and BCD are similar by AA Similarity Theorem
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional
so

substitute the given values



simplify

Answer:
a. 7.2
b. 6
Step-by-step explanation:
Since the side lengths of similar polygons are proportional to each other, therefore:

Thus, let's find b using:

Cross multiply


Divide both sides by 15
b = 6
Let's find a using:

Cross multiply
9*12 = 15*a
108 = 15a
Divide both sides by 15
a = 7.2
