Question

Show that the points A(7,10) , B (-2,5) C(3,4) are the vertices of an isocles right angled triangle. give steps:)

Answer 1

Answer:

ab=(x2-x1)2+(y2-y1)2

=(-2-7)2+(5-10)2

=(-9)2 +(-5)2

=(81)+25

√96

bc=(x2-x1)2+(y2-y1)2

=(3--2)2+(4-5)2

(5)2+(-1)2

25+1

√26 cm

ca=(x2-x1)2+(y2-y1)2

=(3--2)2+(4-5)2

(5)2+(-1)2

25+1

√26cm

ab =ca they are the vertices of isosceles right triangle
