Let's see what this chapter is all about.

We learned about Coordinate Geometry in Class 10. In this chapter, we will

- Revise our
**Coordinate Geometry concepts**(Distance between points, Section Formula, Area of triangle) and solve some questions - What is
**slope of a line**, and different methods to find it (angle, 2 points) - Finding
**angle**between two lines using slope - Checking if
**lines are parallel or perpendicular**, using slope - Proving
**three points collinear**using slope (Slope of AB = Slope of BC) - Then, we study
**equation of lines** - Equation of lines
**parallel to x and y axis** **Slope of lines parallel to x and y axis**- Equation of line when
**1 point and slope**is given - Equation of line when
**2 points**are given - Equation of line when
**slope and intercept**is given(both x intercept and y intercept) - Equation of line when both x and y intercepts are given (Equation of line in
**intercept form**) - Equation of line in
**normal form** **General Equation**of line, and converting any equation into General Form- Finding
**Distance of a point from the line** - Finding
**Distance between two parallel**lines - Distance of a point from a line
**along a line** - Mix
**Questions using all the concepts**
