Algebra A branch of mathematics dealing with manipulation of
symbols, numbers using basic arithmetic operations
FOR ONLINE READING ONLY
Angle Measure of how wide apart two intersecting straight lines are
at their point of intersection

Characteristic The integral part of a logarithm. This is the exponent of 10
when a number is expressed in the scientific form

Equiangular polygon A polygon whose vertex angles are equal. For example a Mathematics for Secondary Schools
square, an equilateral triangle, and rectangle
Hypotenuse The longest side of a right-angled triangle. It is also opposite
to the right angle.

Identities Equations which are true for all values of the variable. This
means that if any value of the unknown is substituted on both
sides, each side gives the same number

Isosceles triangle A triangle with two sides of equal length

Mantissa The part of a logarithm which is located after a decimal point.
Mantissa is always positive
Proportion An expression stating that one quantity is a constant multiple
of another quantity
Quadrilateral A four sided polygon having four sides and four vertices

Reciprocal Inverse of a number, usually obtained by interchanging the
numerator and denominator

Scale factor The ratio between corresponding measurements of the original
object and a new object after enlargement. If the scale factor
is greater than 1, the new figure will be larger. If the scale
factor is a fraction, the new figure will be smaller. A scale
factor is also called enlargement factor
x-y plane A plane that contains two perpendicular coordinates axes x
and y. The x – axis is placed horizontally and y – axis is placed
vertically and they meet at a point called the origin
