Short Answer

Expert verified

If $\bar{D B}$ bisects $∠ C D A$ then $m ∠ 6 ≅ m ∠ 5$ .

Step by step solution

Step 1. Write definition of angle bisector.

An angle bisector is a line segment which divides an angle into two congruent angles, that is, angles with same measure.

Step 2. Description of step.

From the given figure, it can be observe that the $\bar{D B}$ divides $∠ C D A$ into two angles, $∠ C D A$ and $∠ A D B$ , with same measure.

Step 3. Write the two congruent angles formed due to bisector, DB

$\begin{array}{l} m ∠ C D B ≅ m ∠ A D B \\ m ∠ 6 ≅ m ∠ 5 \end{array}$
