Question

see the above picture and answer me . ​

Answer 1

Answer:

Given, DC perpendicular to AC

and DB perpendicular to AB

AC=AB

To prove: DC=DB

Proof:. In ∆ ABD and ∆ ADC

Angle DBA = Angle DCA( Each 90°)

AD = AD( common side)

AC = AB ( given)

Therefore, ∆ ABD is congruent to ∆ADC.

( By RHS congruency)

Hence, DC= DB( cpct)..... proved
