1. Given that AD is perpendicular to BC, this tells us angle ADC and ADB are both right angles and are therefore congruent.

2. We know AD = AD, since it's the same line segment.

3. Since AD bisects angle BAC, we know angle CAD and BAD are congruent.

Based on Angle-Side-Angle, triangles ADC and ADB are congruent.
