Write the quadratic function in VERTEX FORM that has the vertex (-1, -7) and passes through (1, -6)

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.

it is ok do not worry about it my dude. have a good one

  lol
