When gathering information for research we say we are collecting

hint: first 2 letters are "da"

data

Step-by-step explanation:  

when gathering information for research, one of the first things we need to do is collecting data, in order to analyze it and do a preliminary analysis to test the model.

For example, if you are researching about the rain in a given month. We would need to collect the data of how much rains every day, and then analyzing it we can advance with the research.

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.
