Corresponding

Step-by-step explanation:

Explanation:

Corresponding angles are such that they are always on the same side of the transversal line (in this case both are below the transversal line); in addition, they are also on the same side of each of the parallel lines (both angles are to the left of their respective parallel line neighbor).

It's not clear if the angles add to 90 degrees, so we dont know if they are complementary or not. This rules out choice A. The angles are not alternate exterior or interior angles because they do not sit on alternating sides of the transversal line (one angle would have to be above and the other below the transversal for this to happen). So this rules out choices B and D.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
