Question

prove that points ( 4,3) (7,-1) and (9,3) are the vertices of an isosceles triangles​

Answer 1

Answer:

An isosceles triangle is a triangle with (at least) two equal sides.

Formula: Distance between two points= (x2–x1)2+(y2–y1)2−−−−−−−−−−−−−−−−−√(x2–x1)2+(y2–y1)2

A=(4,3)A=(4,3) B=(7,−1)B=(7,−1) C=(9,3)C=(9,3)

|AB|=(7–4)2+(−1–3)2−−−−−−−−−−−−−−√|AB|=(7–4)2+(−1–3)2

|AB|=(3)2+(−4)2−−−−−−−−−−√|AB|=(3)2+(−4)2

|AB|=9+16−−−−−√|AB|=9+16

|AB|=2–√5|AB|=25

|AB|=5|AB|=5

Similarly,

|AC|=(9–4)2+(3–3
