Question

given \\( \triangle a d c \cong \triangle d a b \\). what is the length of side \\( \overline{b d} \\)?

9.5
12.1
20.8
20.8
12.1
9.5
21.6

Explanation:

Step1: Use the property of congruent triangles

Since \(\triangle ADC\cong\triangle DAB\), their corresponding sides are equal.

Step2: Identify the corresponding side of \(BD\)

In congruent triangles \(\triangle ADC\) and \(\triangle DAB\), side \(BD\) corresponds to side \(AC\).

Answer:

\(9.5\)
