Circle in 10th Class Mathematics
a circle. Definition: A circle is the locus of all points equidistant from a central point. Definitions Related to Circles. arc: a curved line that is part of the circumference of a circle. chord: a line segment within a circle that touches 2 points on the circle.

Constructions in 10th Mathematics
In the general sense, construction means to build something. But in geometry it has a special meaning. Here, construction is the act of drawing geometric shapes using only a compass and straightedge. No measuring of lengths or angles is allowed.
Coordinate Geometry (Notes)
The definition of coordinate geometry is the study of algebraic equations on graphs. An example of coordinate geometry is plotting points, lines and curves on an x and y axis.
Traingles in 10th Class
A triangle is scalene if all of its three sides are different (in which case, the three angles are also different). If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral.
Pair of Linear Equations in Two Variables
A solution of a linear equation in two variables ax+by = r is a specific point in R2 such that when when the x-coordinate of the point is multiplied by a, and the y-coordinate of the point is multiplied by b, and those two numbers are added together, the answer equals r.
Quadratic Equations (Notes)
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
Polynomials in 10th Mathematics
A polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate, x, is x2 − 4x + 7.
Real Numbers (Notes)
Real Number. more ... The type of number we normally use, such as 1, 15.82, −0.1, 3/4, etc. Positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers. They are called "Real Numbers" because they are not Imaginary Numbers.
S-Block Elements (NCERT Notes)
s-block elements are the elements found in Group 1 and Group 2 on the periodic table. Group 1 are the alkali metals which have one valence electron. They have low ionization energies which makes them very reactive. Group 2 is the alkali earth metals which have two valence electrons, filling their s sublevel.
Redox Reactions (NCERT)
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
Gravitation (NCERT Notes)
The gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.
Work, Energy and Power (NCERT Notes)
Work, Energy and Power. ... Energy can be defined as the capacity for doing work. The simplest case of mechanical work is when an object is standing still and we force it to move. The energy of a moving object is called kinetic energy
