NO LINKS OR ELSE YOU'LL BE REPORTED! Only answer if you're very good at Math. No guessing please. Look at the figure below. Which of the following statements could be a step in a proof that vertical angles are congruent?​

∠APC ≅ ∠DPB angles adjacent to the same angle are congruent to each other.

Explanation:

Because they share an angle created by P, they are adjacent.

I hope this helped :)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
