Please help me prove that ED is congruent to BA! I thought I had it right by proving right and vertical angles, but I’m missing

Vikki [24]

Step-by-step explanation:

$\overline{DA} \text{ bisects } \overline{EB}$ is given

$\overline{BC} \cong \overline{EC}$ definition of <u>bisect</u>

<u /> $\overline{EB} \perp \overline{ED}, \, \overline{EB} \perp \overline{BA}$ are both given

<u /> $\angle B, \, \angle E \text{ are right angles}$ definition of perpendicular

$\angle B \cong \angle E$ because all right angles are congruent

$\angle{ACB} \cong \angle{DCE}$ vertical angles are congruent

$\triangle{ACB} \cong \triangle{DCE}$ ASA (angle-side-angle)

$\overline{ED} \cong \overline{BA}$ CPCTC (corresponding parts of congruent triangles are congruent)
