Which descriptions from the list below accurately describe the relationship between abc and def? check all that apply.

a. proportional side lengths.

Step-by-step explanation:

In the given figure we can see in ΔABC  and  ΔDEF

∠A=∠D=53°

∠B=∠E=37°

∠C=∠F=90° [right angles]

So by AAA similarity criteria they are similar.

We know that the side lengths of similar triangles are proportional, thus A is correct.

We can see from the figure that all the corresponding sides are proportional but not of same measure.Therefore, they are not congruent and not same.

Only A is the correct option.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

9x
