Question

2 - 3 and 2 - 4 practice geometry (s1 p01 rm h218) sharp, jeffrey / unit 2 - congruence / lesson 2 - 3 congruent triangles, pt 1 6. line de is parallel to line bc. match the correct angle measure to the appropriate angle. angle eac angle dab neither b° c° a°

Explanation:

Step1: Recall parallel - line angle rules

When $DE\parallel BC$, alternate - interior angles are equal. $\angle EAC$ and $\angle ACB$ (angle $c^{\circ}$) are alternate - interior angles.

Step2: Analyze other angle relationships

$\angle DAB$ and $\angle ABC$ (angle $b^{\circ}$) are not equal in a general non - special case. Also, $\angle DAB$ is not equal to $a^{\circ}$ or $c^{\circ}$, and $\angle EAC$ is not equal to $a^{\circ}$ or $b^{\circ}$.

Answer:

Angle EAC: $c^{\circ}$
Angle DAB: neither
neither: $a^{\circ},b^{\circ}$
