Given vertices are not an equilateral triangle.
Given
To show that given values are the vertices of an equilateral triangle.
Value : P ( 2, 3 ) Q ( 1, 5 ) R ( , 4 )
Steps :
( 1 ) Use distance formula to find the gives values consists of equal vertices.
Given all the vertices are equal then move to step ( 2 ).
( 2 ) If the given vertices are equal , then area of an equilateral triangle is,
A =
Using distance formula :
PQ =
P ( 2, 3 ) Q ( 1, 5 )
= 2 ; = 1 ; = 3 ; = 5
=
=
=
PQ =
QR =
Q ( 1, 5 ) R ( , 4 )
= 1 ; = ; = 5 ; = 4
=
= =
Solving above gives
=
QR =
PR =
P ( 2, 3 ) R ( , 4 )
= 2 ; = ; = 3 ; = 4
PR =
=
=
PR = 4
Hence, PQ = ; QR = ; PR = 4
Vertices of all the three sides are different, it is not an equilateral triangle.
Therefore, given vertices are no an equilateral triangle.
