∠DAC=∠BADangle, D, A, C, equals angle, B, A, D. What is the length of \overline{BD}
BD
start overline, B, D, end overline?
Round to one decimal place.

please try. I need this answer to pass my test.

∠DAC=∠BAD

Length of =?

By ASA congruency , the triangle ABD and ACD are similar triangles.

↬Since angle BAD = Angle DAC , the side AD is typical for the two triangles , and Angle BDA = Angle CDA = 90 degrees.

⇰Therefore ,the congruent sides are proportional.
