No A reflection preserves only lengths of sides.
Yes. A reflection preserves both angle measures an lengths of sides.
No. A reflection preserves neither angle measures nor lengths of sides.

step-by-step explanation:

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
