Question
In $\triangle\text{ABC},$ AB = AC and $\text{AD}\bot\text{BC},$ then BD = _____.
✓

Answer

In $\triangle\text{ABC}:\text{AB}=\text{AC},\text{AD}\bot\text{BC}$ Then, $\text{BD}=\underline{\text{DC}}$

Solution:

$\text{BD}=\text{DC}$

This is because in an isosceles triangle, the perpendicular dropped from the vertex joining the equal sides, bisects the base.
