Answer 2

Given Information

The given information states that on figure 48, AB = BC and angle 1 = angle 2.

Proof of Angle Equality

To prove that angle ADB = angle CDB, we can use the fact that opposite angles of a parallelogram are equal.

Proof Steps

1. Given: AB = BC and angle 1 = angle 2 2. In parallelogram ABCD, opposite sides are equal and opposite angles are equal [[8 #]]. 3. Therefore, angle ADB = angle CDB.

So, angle ADB = angle CDB.

This proves that the angles ADB and CDB are equal based on the given information and the properties of a parallelogram.
