Alexa is constructing a circle inscribed in a triangle. She has partially completed the construction as shown below. What should be her next step in the construction?

Question

anonymous · Answer

a. Connect vertex B to the arc marking to complete the angle bisector 
b. Use the compass to find the angle bisector for angle A 
c. Connect three arc markings together to form the triangle 
d. Use the arc markings to determine the radius to construct the circle

@chantz417   The center of a circle that can be inscribed in a triangle is the point of intersection of the angle bisectors. You have on the drawing the construction of one angle bisector. What do you think you should do next - look at the options. 

Post what you think is the correct option, okay?

i think it is c

I don't think so because "c" mentions joining arcs to form a triangle. We are drawing a circle. We need the center of that circle. To get that center, we need the point of intersection of two angle bisectors of the triangle.

Try again.

a? @Directrix

No. Try again.  Which option says to construct an angle bisector?

directrix · Answer

@chantz417   Think "Use the compass ......"

b does that was the one i was thinking about saying but i wasnt sure

directrix · Answer

B is what I got. You need that second angle bisector to get its intersection with the first angle bisector to find the center of the inscribed triangle.
