##### Workshop    Ploygon Angles  Level 1Level 2  Gallery

You will be awarded a trophy if you get at least 7 questions correct and you do this activity online.

 1 Which regular polygons tessellate? triangles :: quadrilaterals :: pentagons :: hexagons heptagons :: octagons :: nonagons :: decagons ☐ ☐ ✓ ✗ 2 Imagine a tessellation of trapezia where each edge of one trapezium is aligned along an edge of the same length of another trapezium. How many trapezia will meet at any junction point in the tessellation? ☐ ☐ ✓ ✗ 3 Imagine a tessellation of scalene triangles where each edge of one triangle is aligned along an edge of the same length of another triangle. How many triangles will meet at any junction point in the tessellation? ☐ ☐ ✓ ✗ 4 Tessellations can be made using two different regular polygons. Which other polygon would complete a tessellation including octagons? ☐ ☐ ✓ ✗ 5 Tessellations can be made using two different regular polygons. Which other polygon would complete a tessellation including dodecagons? ☐ ☐ ✓ ✗ 6 Which pentominoes tessellate? pentomino F :: pentomino I :: pentomino L :: pentomino N pentomino P :: pentomino T :: pentomino U :: pentomino V pentomino W :: pentomino X :: pentomino Y :: pentomino Z ☐ ☐ ✓ ✗ 7 Which 7-pin polygons tessellate? polygon #1 :: polygon #2 :: polygon #3 :: polygon #4 :: polygon #5 polygon #6 :: polygon #7 :: polygon #8 :: polygon #9 :: polygon #10 polygon #11 :: polygon #12 :: polygon #13 :: polygon #14 :: polygon #15 polygon #16 :: polygon #17 :: polygon #18 :: polygon #19 :: ☐ ☐ ✓ ✗ 8 What is the sum of the angles (in degrees) of the vertices that come together at a point in an edge-to-edge tessellation? ☐ ☐ ✓ ✗ 9 In a particular semiregular tessellation four regular shapes come together at each point. If two of the shapes are squares, the third is a triangle, what is the name of the fourth polygon? ☐ ☐ ✓ ✗ 10 In a different semiregular tessellation three regular shapes come together at each point. If one of the shapes is a square, the second is a hexagon, what is the name of the third polygon? ☐ ☐ ✓ ✗

## Instructions

Try 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 18 September 'Starter of the Day' page by Mrs. Peacock, Downe House School and Kennet School:

"My year 8's absolutely loved the "Separated Twins" starter. I set it as an optional piece of work for my year 11's over a weekend and one girl came up with 3 independant solutions."

Comment recorded on the 28 May 'Starter of the Day' page by L Smith, Colwyn Bay:

"An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!"

Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month.

The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing.

Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page.

#### Bidmaze

Find your way through the maze encountering mathematical operations in the correct order to achieve the given total. This is an addictive challenge that begins easy but develops into quite a difficult puzzle.

There are answers to this exercise but they are available in this space to teachers, tutors and parents who have logged in to their Transum subscription on this computer.

A Transum subscription unlocks the answers to the online exercises, quizzes and puzzles. It also provides the teacher with access to quality external links on each of the Transum Topic pages and the facility to add to the collection themselves.

Subscribers can manage class lists, lesson plans and assessment data in the Class Admin application and have access to reports of the Transum Trophies earned by class members.

## Go Maths

Learning 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.
