Incenters. (Geometry) Have to find measures. Picture being uploaded.
I am trying to fine AU. And Angle ARU. I think i have what i need for AU. Just need some confirmation.
Since TA is 20. I started thinking about the Bisecting thing. And I am saying that AU is also 20. Because KP bisects in Angle TAU
...Am i right on that?
yes, AU is 20, but how did u prove it ?
Well i kind of thought through it. Since the lesson is about Bisectors. I gave a thought that angle TAU was being bisected by KP. And if angle TAU was being bisected, and TA was 20; then AU must also be 20.
that can be proved by proving triangles congruent just saying will not be enough IF u need to show your work.
else reasoning is correct
Ok! And how should i figure out what the measure of angle ARU is? I am stuck there.
thats even simpler, AR bisects angle R
OH!!! SO then 40 degrees?
