Geometrical vocabulary

If you want to understand all maths questions involving Geometry and want to be able to confidently find the size of angles, construct figures, find lengths in various polygons etc, then you need to know the language. The following videos discuss all the keywords necessary for you to be familiar with to understand Maths and especially Geometry. The example maths questions will explain step by step to you for instance what a reflex angle, decagon, isosceles triangle etc is. Study the maths videos therefore carefully for your Maths revision and prepare yourself well for your Maths exam! If you don't understand Geometry, then let me know on the forum on the homepage of this site and i will help you with your maths. Good luck and have fun!

What are Acute, Right, Obtuse and Reflex Angles

In this maths video we will have a look at different types of angles. What is an acute angle and what is the difference between an obtuse and a reflex angle? All these questions will be answered in the following maths activity.

What are Isosceles, Equilateral and other types of Triangle

Have a look at the next maths resource in which we will discuss different types of triangles. What is the difference between an Isosceles triangle and an Equilateral Triangle? We will also have a look at other types of triangles

What are Polygons; Hexagon, Heptagon, Octagon, Nonagon etc

If you want to understand Geometry, you will need to know the language used. The next maths video will show you the names of all polygons which you need to know. Do you know how many sides and how many angles a pentagon, hexagon, heptagon, octagon, decagon and dodecagon for instance have? After looking at the next video you will! Do you know the special name for a 9-sided polygon?

What are Quadrilaterals; Trapezium, Rhombus, Kite, Parallelogram etc

In this video we will have a look at all sorts of Quadrilaterals. A quadrilateral is a 4-sided polygon. I am sure you know what a square is, but I am also quite sure that you will have difficulties giving an accurate definition or description of a square. Look at the next maths video in which we will accurately describe and discover what a square, rectangle, parallelogram, rhombus, trapezium and kite are.

What are Chords, Segments, Sectors, Diameters, Radius etc

There are many important keywords regarding circles you need to familiarise yourself with. What is a chord, segment, sector, radius and diameter of a circle? After looking at the following video you will know the answer to all these maths questions. Perhaps it is an idea to make a summary sheet with all the important maths language and keywords you have learned so far!

What are Congruence and Similarity and what is the difference

What is Congruence and what is Similarity? Some people think the to terms mean the same. However, they are not! Congruent figures are identical. All corresponding angles and sides are equal. Similar figures are not identical. Similarity means that corresponding angles are the same in size and corresponding sides are in proportion. Have a look at the next video for more information about Congruence and Similarity.

Congratulations! You are now familiar with all ht important words needed to understand geometry. Continue with your maths revision and learn how to construct various polygons. Follow the link where I will explain to you how to construct these polygons using a protractor, rules and compass. I will see you there!
