I need to find the midpoints of each side of the triangles. and draw perpendicular bisectors

Question

this what i have A(8,-2) B(-10,-8) C (-2,8) I connected it into a triangle like it said then I need to find the midpoints of each side of the trangles then draw the perpendicular bisectors and it says the slopes must be opposite reciprocals.

Answer 1

1. if 2 lines be perpendikular (90 deg apart), slope2=-1/slope1

2. yer 3 points...triangel hav sidle lengths av 11.661904, 17,888544, & 20,59126

angels =34.38035, 94.39871, 51.22094  degrees

sampel side...from (-10,-8) tu (-2,8)...deltax=8, deltay=16, slope=deltay/deltax=16/8=2

perp line will hav slope=-0.5

midpoint av this line...x=(-10-8)/2=-18/2=-9....y=(-8, +8)=0...0, so midpoint=(-9,0)

yu kan then kalk formula for this line
