Question 1: Find equation of the perpendicular bisector of segment joining the points (2,-5) and (0,7)? Equation of a parabole is . Coordinate Geometry Formulas: Now, Let us have a look at some formulas for coordinate geometry. A tangent to a circle is a straight line that just touches it. Circle formula. In particular it is central to the mathematics students meet at school. A strong command over the formulae / concepts covered in this sheet is a must for understanding the chapters / topics that follow, i.e. This arsenal of tools is far more extensive than that of many other computational techniques. Equation of a line is ; Equation of a circle is , where r is the radius of a circle. We define a diameter, chord and arc of a circle as follows: Ł The distance across a circle through the centre is called the diameter. The normal to a circle is a straight line drawn at $90^\circ $ to the tangent at the point where the tangent touches the circle.. Straight Line, Circle, Parabola, Ellipse and Hyperbola. For example, in a ne geometry every tri-angle is equivalent to the triangle whose vertices are A0 = (0;0), B0 = (1;0), C0 = (0;1) (see Theorem 3.13) and in Euclidean geometry every triangle is Perpendicular lines.
