Heyo! I did this a little while ago, so I can confirm this is valid as of 5.20.22. for the practice assessment.
_______________________________________________________
~Bisectors in Triangles~__________________
- 1.) B - Concurrency of Perpendicular Bisectors Theorem
- 2.) B - F is the incenter of the triangle, D - F is the point of concurrency of the angle bisectors of the angles of the triangle, and F - F is equidistant from the three sides of the triangle.
- 3.) B - Right
- 4.) B - (1.5, 1)
- 5.) D - (3.5, 3)
- 6.) Part A: A - Isosceles
- Part B: D - 122°
- 7.) C - 80°
- 8.) Part A: A - x = 2
- Part B: D - 7 units
Hope this helps! Is so, please lmk!
