Any One Wanna Take A Shot At This : Geometry

OpenStudy (anonymous):

Which statement can be used to fill in the numbered blank space? ∠DBA ≅ ∠CDB ∠CAB ≅ ∠ACB ∠ABD ≅ ∠CBD ∠BDA ≅ ∠BDC

OpenStudy (acxbox22):

Give me a gun

OpenStudy (anonymous):

LMAO -Hands you a gun-

OpenStudy (acxbox22):

Sorry i have a brief idea of this but I am not a Geometry master

OpenStudy (anonymous):

Thats Fine, Thanks for looking on it

OpenStudy (anonymous):

We see that the 'reason' given is 'definition of angle bisector', if we look at part one we see that they constructed AD, the bisector of ABC So tell me, what does a bisector do?

OpenStudy (anonymous):

A line that splits an angle into two equal angles

OpenStudy (anonymous):

good, so which angle is the bisector AD that they constructed bisecting?

OpenStudy (anonymous):

BD

OpenStudy (anonymous):

oops I mistyped, which angle is BD bisecting*

OpenStudy (anonymous):

Uhh , I'm sorry I'm Not Sure :(

OpenStudy (anonymous):

its right there in the statement of part 1

OpenStudy (anonymous):

it is the bisector of ABC, do you see where it says that in the first line of the table

OpenStudy (anonymous):

Oh Ok Yes

OpenStudy (anonymous):

So if u look at the triangle I want you to visual a vertical line straight down from B, which connects to the midpoint of the base of the triangle (is the edge AC) Do you see how that is the bisector we are talking about?

OpenStudy (anonymous):

Ok Yes

OpenStudy (anonymous):

good, so this bisector split the angle ABC into 2 smaller angles, which will be equal (because thats what a bisector does) what are these 2 angles?

OpenStudy (anonymous):

OpenStudy (anonymous):

ABD CBD

OpenStudy (anonymous):

Well done ;)

OpenStudy (anonymous):

Thanks Buddy!
