Angles MixedFind the unknown angles in these diagrams which are not drawn to scale |
This is level 1: basic questions on angles together on a straight line, angles at a point, angles in a triangle and a quadrilateral. You will be awarded a trophy if you get at least 9 correct and you do this activity online.
InstructionsTry your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help. When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file. |

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School: "What a brilliant website. We have just started to use the 'starter-of-the-day' in our yr9 lessons to try them out before we change from a high school to a secondary school in September. This is one of the best resources on-line we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun." Comment recorded on the 8 May 'Starter of the Day' page by Mr Smith, West Sussex, UK: "I am an NQT and have only just discovered this website. I nearly wet my pants with joy. |

Go MathsLearning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school. Maths MapAre you looking for something specific? An exercise to supplement the topic you are studying at school at the moment perhaps. Navigate using our Maths Map to find exercises, puzzles and Maths lesson starters grouped by topic. | ||

The video above focusses on the angles in a triangle. You will also need to know the other Angle Theorems.
Angles at a pointThe sum of the angles that fit around a point is 360°. a° + b° + c° = 360° |
|
Angles on a straight lineThe sum of the angles that fit on a straight line 180°. a° + b° = 180° |
|
Vertically opposite anglesWhere two straight lines cross vertically opposite angles are equal. a = b |
Alternate anglesThis diagram shows pairs of alternate angles which are equal |
|
Corresponding anglesThis diagram shows pairs of corresponding angles which are equal |
A reminder of the Circle Theorems here.
