Question

complete each statement to show why △dea ~ △cba. step 1: ∠dea is congruent to ∠cba because they are both right angles. step 2: ∠ead is congruent to ∠bac because they are? angles.

Explanation:

∠EAD and ∠BAC are formed by the intersection of two lines (the lines containing DE and BC, and the line containing EA and BA). When two lines intersect, the opposite angles formed are vertical angles, and vertical angles are congruent. So ∠EAD is congruent to ∠BAC because they are vertical angles.

Answer:

vertical
