PLS HELP The figure below shows parallel lines cut by a transversal:

Which statement is true about ∠1 and ∠2? (4 points)

a
∠1 and ∠2 are complementary because they are a pair of corresponding angles.

b
∠1 and ∠2 are congruent because they are a pair of corresponding angles.

c
∠1 and ∠2 are complementary because they are a pair of alternate interior angles.

d
∠1 and ∠2 are congruent because they are a pair of alternate interior angles.

B and D

Step-by-step explanation:

I don't have much of an explanation, but I remember from taking geometry that those two angles are the same measurement because they're congruent interior angles. hope this helps :)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
