Answer 3

I'm sorry but this one I dont understand

Answer 4

oh ok

Answer 5

How can you check if a segment is an angle bisector of a triangle?

Check if measures of the two angles the segment divides the vertex angle into are the same.

Check if the areas of the two triangles the segment forms are equal.

Check if the segment meets a side of the triangle at a right angle and divides the vertex angle into two congruent angles.

Check if the segment meets a side of the triangle at a right angle and divides the side into two congruent parts.

Answer 6

This would be easiest for you to visualize if you were to draw the segments they are asking about.
I would also recommend refreshing your memory on the definition of a perpendicular bisector.
