To find the slope of a line using 2 points on that line, you use the equation <em>m = y₂ - y₁/x₂ - x₁</em>, where <em>(x₁, y₁) and (x₂, y₂) </em>represent 2 random points on the line.
If an angle of 1 isosceles triangle is congruent to an angle of another isosceles triangle the triangles are similar. sometimes If the corresponding sides of 2 similar triangles are in a ratio of 3:4 then the there perimeters are in a ratio of 3:4. brainlist
