Q:
prove that the three points A(-5,0) B(3,0) and C(-1, 4√3) are the vertices of an equilateral triangle
-----------------------------------------------------------------------
A:
Using distance formula:
AB = = 8
AC = = 8
BC = = 8
All three sides are equal, therefore A, B, and C are the vertices of an equilateral triangle. ■
