Geometry help please? G is the incenter of Δ ABC. m∠A = 58 m∠B = 64 m∠C = 58 What is the m∠BCE? 36 27 32 29
picture ina sec
How do I solve this?
that can't be right i ended up with 119 :l
What do you know about incenters?
m∠A = 58 m∠B = 64 m∠C = 58 The triangle has it's 3 Medians marked(D,E,F). A median cut's exactly half way from a vertex to the opposite side... It bisects the line segment and angle. So angle BCE would be half of angle C's measurement.
its 29?
Yes.
yea because it wants angle c... And C is bisected so its halfed
i think angle at C is getting bisect.. which means its dividing the angle in half.. so just half the angle of C
which is 29
Exactly. :D
thanks guys :)
welcome (:
yea it was 29 I just sent my quiz
@jazy, the incenter is the intersection of the angle bisectors. The medians are not involved. "A median cut's exactly half way from a vertex to the opposite side... It bisects the line segment and angle." This statement is false.
yes incenter is the bisectors and circumcenter is the perpandicular bisectors. I do not know where the medians are involved
what is the median of a triangle?
A median bisects a side of the triangle, but it doesn't necessarily also bisect the angle. |dw:1350322892891:dw|
In triangle ABC (that I drew), AN is an angle bisector and passes through the incenter of the triangle. CM is a median and makes AM = MB. It is not also an angle bisector of ACB. ACM =/= MCB.
lagged
|dw:1350323109326:dw| correction to the drawing.
I see so it intersects at the middle of a line but doesnt always bisect
Medians bisect sides. The three medians intersect at the centroid. Angle bisectors bisect angles. The three angle bisectors intersect at the incenter.
alright i got yea
Play around over here for a while http://www.mathopenref.com/triangleincenter.html @jazy you too.
k, thanks for the explanation @CliffSedge (:
