Question

Show that the following points form a equilateral
triangle A(a,0), B(-a, 0), C(0, a √13)​

Answer 1

Answer:

give a(a,0),B(-a,0),C(0,a√3).

AB=√(a-(a))2+(0-0)2= √4a2=2a

BC=√(0-(-a))2+(a√3)2=√4a2=2a

CA=√(0-(-a))2+(a√3)2=√4a2=2a

Step-by-step explanation:

.°.AB=BC=CA

Hence,it is an equilateral triangle,
