If two similar polygons have a scale factor of 1, what can you conclude? a. they are sometimes congruent. b. they are always congruent. c. they are never congruent. d. they would only be congruent if they were regular polygons.

answear:

a

step-by-step explanation: a

ab will be equal to

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.

here the answers ur welcome also plz mark as brainliest if someone else anwers
