The distance between the points A(x, y) and B(x2, y2) is given by AB=√(x2-x)²+(y₂-Y₁)². 2. The distance of the point P(x, y) from the origin O(0, 0) is given by OP = √x²+ y². TWO IMPORTANT NOTES (i) Any point on the x-axis is of the form (x, 0). (ii) Any point on the y-axis is of the form (0, y). PROPERTIES OF VARIOUS TYPES OF QUADRILATERALS A quadrilateral is a (i) rectangle if its opposite sides are equal and the diagonals are equal. (ii) square if all its sides are equal and the diagonals are equal. (iii) parallelogram if its opposite sides are equal. (iv) parallelogram but not a rectangle if its opposite sides are equal and the diagonals are not equal.. (v) rhombus but not a square if all its sides are equal and the diagonals are not equal. SECTION FORMULA DEOREM 2 (Section formula) The coordinates of the point P(x, y) which divides the line segment joining A(x, y) and B(x, y) internally in the ratio m:n are given by x=mx2+nx1/m+n y=my2+ny1/m+n AREA OF A TRIANGLE The area of a triangle ABC with vertices A(x, y), B(x, y) and C(x,y) is given by Area(AABC)=1/2(x1 (Y₂-Y3)+X2 (Y3-Y₁) + X3 (y₁−y2)
