Degree of Polynomial

Degree can mean several things in mathematics: In Geometry a degree (°) is a way of measuring angles, In Algebra “Degree” is sometimes called “Order” Degree of a Polynomial A polynomial looks like this: 2×3 + 3×2 + x -1 The Degree (for a polynomial with one variable, like x) is the largest exponent of that variable.

Definition The exponent of a number says how many times to use the number in a multiplication. In 42  the “2” says to use 4 twice in a multiplication, so 42 = 4 × 4 = 16 In words: 42 could be called “4 to the power 2” or “4 to the second power”, or simply “4

Solving SSS Triangles

Definition SSS means “Side, Side, Side” When we know 3 sides of the triangle, we can find the missing angles. How To Solve SSS Triangle To solve SSS triangle: use The Law of Cosines to calculate one of the angles use The Law of Cosines to find another angle use angles of a triangle add


Cuboids are familiar objects you encounter in daily life numerous times. Cuboids are essentially boxes, formed exclusively from rectangles. These familiar shapes are also known as rectangular prisms. Definition of Cuboid The cube is a 3D structure which is formed when 6 identical squares bind to each other in an enclosed form. Remember all cubes

Pascal’s Triangle: Definition, Pattern, Formula, Example

Mathematics identic with numbers. Some of them have special pattern. It is not only arithmetic and geometry sequences but also truly special pattern. One of them is Pascal’s triangle. In real life it can be applied to solve combination of head and tail problems, polynomials problem (binomial expansion), etc.. Definition of Pascal’s Triangle Pascal’s triangle

Supplementary Angles

Definition 2 Angles are Supplementary when they add up to 180 degrees. Supplement comes from Latin supplere, to complete or “supply” what is needed. These two angles (120° and 60°) are Supplementary Angles, because they add up to 180° and make a straight angle. But the angles don’t have to be together. These 2 angles

Vertically Opposite Angles

Vertically Opposite Angles Definition Vertically Opposite Angles are the angles opposite each other when 2 lines cross Vertical in this case means they share the same corner point (vertex), not the usual meaning of up-down. a and c are vertically opposite angles. b and d are also vertically opposite angles. The interesting thing here is that vertically opposite angles are

Conditional Probability: Dependent Events, Formula, Examples

Dependent Events Dependent events mean two or more events that occurred after the first or other events has already occurred. For examples there are dependent events in real life: Two times of taking marbles but the first is without replacement, then the second time number of marbles is change. There are three choices of a

Squares and Square Roots

How to Square A Number To square a number: Multiply the number by itself. “Squared” is often written as a little 2 like this: 42 = 16 This says “4 Squared equals 16“ (the little 2 says the number appears twice in multiplying) Perfect Squares The Perfect Squares (also called “Square Numbers“) are the squares of

Congruent Angles

In geometry, 2 figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. Definitions of Congruent Angles Angles are congruent if they have the same angle measure in degrees. They can be at any orientation on
