(Q3) The side BC of an equilateral △ABC is parallel to X-axis. Find the slopes of line along sides BC,CA and AB.

ABCXYO60o60o60o

Given:△ABC ; BC // X-axis.

Slope of BC = tanθ

Where θ is the angle made of BC with +ve X-axis = tan '0' = '0'

Slope of AB = tan 60° = √

[∵ Each angle of an equilateral triangle is 60°]

Slope of AC = tan 60° = √
