Vertices of RT

Show that the points P1 (5,0), P2 (2,1) & P3 (4,7) are the vertices of a right triangle.

Correct answer:

x =  0

Step-by-step explanation:

x1=5 y1=0 x2=2 y2=1 x3=4 y3=7 a=(x1x2)2+(y1y2)2=(52)2+(01)2=103.1623 b=(x1x3)2+(y1y3)2=(54)2+(07)2=5 27.0711 c=(x2x3)2+(y2y3)2=(24)2+(17)2=2 106.3246 x=b2(a2+c2)=7.07112(3.16232+6.32462)=0
