The distance ‘d’ between any two locations on the coordinate axis, A (x1,y1) and B (x2,y2), is determined by NCERT Solutions for Class 12 Maths.
d = (x2 – x1)2 +(y2 – y1)2
- Distance between Two Points on a Line
Assume a line ax+by+c=0 and a point P(x1,y1). Then the distance ‘d’ between point P and the line will be determined by maths concepts – Learn Important Mathematics Concepts
- Distance between Two Parallel Lines
Assume there are two lines, line 1 ax+by+c=0 and line 2 ax+by+c’=0. Then the ‘d’ distance NCERT Solutions for Class 11 Maths between both the lines will be determined by:
The coordinates of point D when it is divided by line AB in the ratio m: n will be determined by:
Area of Triangle
There are numerous formulas for calculating the area of a triangle. The formula Maths Concepts – Learn Mathematics topics to use is determined by the information provided in the statement.

Case II: If point coordinates are provided. Assume A(x1, y1), B(x2, y2), and C. (x3,y3 ). Then there’s Area ‘A’ will be determined by:
Equation of Straight Line
Case 1: Point-Slope Form
Assume ‘m’ is the slope of the line. Now let the line pass through point A. (x1,y1). Then the equation of the line NCERT Solutions for Class 12 Maths will be determined by:
Case 2: Point-Point Form
Allow a line to pass across positions A(x1,y1) and B. (x2,y2). Then the line equation will be determined by:
Case 3: Slope-Intercept Form
Assume the slope of the line be ‘m,’ and the intercept on the y-axis be ‘c.’ Then the line equation will be determined by Maths Concepts – Learn Mathematics topics.
Case 4: Intercept Form
Allow the line to have intercepts’ a’ and ‘b’ on the x- and y-axes, respectively. Then the line equation will be determined by:
Case 5: Standard Form

Collinearity of Points
Points A(x1,y1), B(x2,y2), and C(x3,y3) are collinear only if,
Angle formed by Two Lines
Let us assume m1 and m2 to be the slopes of two lines. The angle formed by two lines will be determined by:
The point’s position in relation to the line:
- Position of points A(x1,y1) and B(x2,y2) with respect to the line ax + by+c=0.
- If both ax1+by1+c1=0 and ax2+by2+c2=0 have the same signs, then points A and B will lie on the same line; otherwise, they will lie on the opposite side of the line.
Locus of Point
When a point shifts from its location to satisfy a specific requirement or criteria, its path is referred to as its Locus Maths Concepts – Learn Mathematics topics.
- The use of coordinates JEE Main 2022 Maths Syllabus to represent the locus of a point in two-dimensional space:
- To calculate the coordinates of a point D in two-dimensional space for the origin. The OXY axes are an ordered pair of real integers expressed as (x, y). The coordinates are the distances from the origin of the foot of the perpendiculars from the point P on the respective cartesian coordinates.
- The origin coordinates are (0,0).
- Equation of a curve/ region:
- The equation of curve/region depicts the relationship seen between coordinates of every point on the curve/region, which holds for no other points beyond those on the curve/region.
- The x-axis equation is y = 0; the y-axis equation is x = 0.
