Composed of separate parts

A structure or an entity made up of distinct components.CompositeCompoundNot simpleA complex material

From Latin compositus, to put together Is measured in square unitsAreaDifferent for each shape Involves multiplicationJ. Q area

The size of a surfaceIs measured in cubic unitsVolume control on a radioInvolves multiplication

Involves 3 dimensional figuresThe amount of space inside a containerPut the volume downperimeter

The distance around the shapeCircumferenceInvolves addition

the external boundary or surface of a figure or object .from Latin circumferentia, from circumferre to carry around, from circum- + ferre to carry more at bear Substitute

TrigonometryReminds me ofthreeIt is made up of two wordsMetry or measurementtriangleStudents add their ownTrigonometryIs usedIs used in navigationengineeringconstructionastronomySurveying landRatioA ratio is a comparison of like quantitiesRatios are just like fractions3 to 5 is an example of a ratioWe write ratios in 3 different ways3 to 53:5Each term is expressed in the same unite, then unite re left out.Ratios are usually writtenin their simplest form.Perimeterto measurePeriFor 2D shapesmeterdistance around a shapeThe units are mm,cm, m , kmIt is called circumference for circlesMade of two wordsinvolves additionIs measured in square unitsAreaDifferent for each shape Involves multiplicationThe backyard area

The size of a surfacePrior knowledgeWhat is area?Mean, Median Mode and Range MiddleAverageMost frequentDifferenceReal life application of coordinate geometryFor finding the distance between the places In Geography also it has many applications In astrophysics to find the distance between the planets, coordinate geometry helps.For everyday activities: reading street directoriesFor monitoring of traffic flow, coordinates provide an accurate method for indicating position.For locating points and finding the distance between two pointsCommissionIncomesTaxesProfits or lossesGoods and services (GST)(Goods and services tax) is a fee charged on things imported and sold. The rate is 10%.A fee charged by a government on a product, income, or activity.Commission is a fee which a salesperson would receive upon completion of a sale.The gain or the loss of something. Money received esp. on a regular basis for work.The opposite of any event is its complement.Complementary The complement of winning is losingThe opposite

for getting a 4 on a roll of a die, the complement is getting a 1,2,3,5 or 6 We us the word complement in the topic probabilityIs Prism

PolygonsThey are made of straight linesExample: quadrilateral

A polygon is a plane shape with straight sidesPolygons are 2-dimensional shapesthe shape is "closed" (all the lines connect up)Some words in maths that are used in other subjectsBar value variablePieAscendingDescendingPrimeConsecutiveBaseExteriorExpandEvaluateSimplifySumProductComplementarySupplementarySimplifyReduce factorComposite
