`        The centriod of equilateral triangle is an origin and one of the side equation x+y=2. Find equations of other sides. `
11 months ago

```							Dear student The perpendicular bisector of the given side is y = xThen intersection of the bisector and the line x+y = 2 is at (1,1) The distance from the centroid to the vertex on y = x is 2x the distance from the origin to the line --> the vertex is at (-2,-2)The slope of x+y=2 is -1 --> the tangent of the angle with the x-axis = 135 degsThe angles of the 2 other sides with the x-axis are 75 degs and 195 degs. The slope of a line = the tangent of the angle with the x-axis.Tan(195)=2-root3=slopey + 2 = (2 - sqrt(3))*(x + 2) eqn of 1 line
