When three vertices of a parallelogram

When three vertices of a parallelogram are given, the fourth vertex can be found using the property that opposite sides are parallel and equal. If ver

For any two points A(x₁

For any two points A(x₁, y₁) and B(x₂, y₂), the midpoint M is given by: M = ((x₁ + x₂)/2, (y₁ + y₂)/2). This formula works by taking the average of co

When a point P divides

When a point P divides the line joining A(x₁, y₁) and B(x₂, y₂) in the ratio m:n internally, then P = ((nx₁ + mx₂)/(m+n), (ny₁ + my₂)/(m+n)). The form

For two points A(x₁

For two points A(x₁, y₁) and B(x₂, y₂), slope m = (y₂ - y₁)/(x₂ - x₁). Slope represents the rate of change of y with respect to x. Positive slope mean

A line can be represented algebraically

A line can be represented algebraically in several forms: Point-slope form: y - y₁ = m(x - x₁); Slope-intercept form: y = mx + c; Two-point form: (y -
