How do you figure out Rotational Symmetry?Rotational SymmetryIf a shape can fit exactly into itself after a certain rotation (not a full one) about a fixed point (called centre of rotation) then it is said to have rotational symmetry. The angle of turnin…

What are the Types of Relations in Set TheoryRelationsDefinition : Let A and B be two non-empty sets, then every subset of A × B defines a relation from A to B and every relation from A to B is a subset of A × B. Let R ⊆ A × B and (a, b) ∈ R. Then we say…

Algebraic ExpressionAny combination of literal numbers or variables and numbers (numerals) connected by +, –, × or ÷ signs is called an algebraic expression. For example, 5, 6x, a + b × c, 4 × m + n, x – y ÷ z are algebraic expressions. The perimeter P o…

How to Multiply Matrices Multiplication of matricesTwo matrices A and B are conformable for the product AB if the number of columns in A (pre-multiplier) is same as the number of rows in B (post multiplier). Thus, if A = [aij]m×n  and B = [bij]n×p are t…

What are Parallel lines and Transversals? Parallel lines:Two lines l and m are said to be parallel if (i) they lie in the same plane (ii) they do not intersect when produced indefinitely in either direction and we write l || m (which is read as ‘l is pa…

HyperbolaA hyperbola is the locus of a point in a plane which moves in the plane in such a way that the ratio of its distance from a fixed point in the same plane to its distance from a fixed line is always constant which is always greater than unity. …
