?????????????????? "altitide" ??????????
???? yu gonna fli plane inside thr triangel ???????
me assume yu want the HITE, but kant duit yer wae
Hite go from a SIDE, not from a point
The base=longest side=from (-3,7) tu (+3,-5)
deltax=6, deltay=12, leng=sqrt(6^2+12^2)=sqrt(36+144)=sqrt 180=13.41640786
side2...from (-3,7) tu (5,1): deltax=8, deltay=6...leng=sqrt(8^2+6^2)=sqrt(64+36)=sqrt(100)=10
side3...from (3,-5) tu (5,1); deltax=2, deltay=6...leng=sqrt(4+36)=sqrt(40)=6.32455532
now, kan make resunabel triangel from 3 side lenths
Hite=4.47236
triangel area=30.00074, rimleng=29.74063
top=(4.47192, 4.47236
