ملخص الدرس

This lesson provides an extensive treatment of linear equations, polygon areas via 3x3 determinants, centroid calculation, perpendicular distances from points to lines, and concurrency criteria for triple lines.

هتتعلم إيه فى الدرس ده

• Standard forms of line equations (general, point-slope, slope-intercept, intercept form).
• Calculating triangle areas using matrix determinants.
• Centroid coordinates G of a triangle as the mean of vertex coordinates.
• Perpendicular distance formula d = |Ax0 + By0 + C| / \sqrt{A^2 + B^2}.
• Concurrency condition for three straight lines via determinant vanishing.
