Question

From the diagram below, we can tell that Δ ABC is similar to ____.

Answer 1

From the diagram, we get that

`\measuredangle ABD\cong\measuredangle ADB.`

By the reflexive property of congruence, we know that:

`\measuredangle A\cong\measuredangle A.`

Therefore, by the Angle-Angle criterion:

`\Delta ABC\sim\Delta ADB.`

Answer:

`\Delta ADB.`
