  1. This figuire is also a tesselation. A tesselation is a shape with no gaps. Regular or Irregular Coming Attractions: hexagon regular If its regular then it fits together with no gaps.

  2. Parallel lines Right know we have to find the sum of the angles. So that means that the other 2 hexagons have 3 pairs of parallel lines. This is a pair of parallel lines. Parallel lines are lines that seem to never touch. One figure has 3 pairs of parallel lines. These are all the pairs of parallel lines. 9 pairs of parallel lines

  3. What is the measure of each angle? Explain • 8. Does this polygon tessellate? Explain

  4. 3 sides – 2 = 1 x 180= 180 360 4 sides – 2 = 2 x 180= 360 540 pentagon 5 sides – 2 = 3 x 180= 540 6 hexagon 7 7 900 8 octagon 9 9 1260 1440 10 decagon

  5. Pentagon has 3 triangles in it. 2 2 3 1 1 Rectangle has 2 triangles in it. 1 hexagon has 4 triangles in it. 2 4 3 3 5 4 1 2 heptagon has 5 triangles in it.

  6. Pentagon has 3 triangles in it. The sum of the angles is 360. 180 180 180 The sum of the angle is 540. 180 180 Rectangle has 2 triangles in it. 180 hexagon has 4 triangles in it. The sum of this angle is 710. 180 180 180 180 180 180 180 180 The sum of this angle is 890. heptagon has 5 triangles in it.

  7. 3 sides – 2 = 1 x 180= 180 4 sides – 2 = 2 x 180= 360 pentagon 540 5 sides – 2 = 3 x 180= 540 6 hexagon 7 7 900 8 octagon 9 9 1260 10 decagon 1440 10. What would be the sum of the angles in a 52 sided polygon?

  8. The degree of this angle is 85. ????? 85 50 45 180 – 45 = 135 – 50 = 85 Whatever you have on the sides of the angle you subtract by 180. A straight line is always 180.

  11. Use auto shapes to draw a tessellation below This illustration is a tessellation because……. It is a picture with no gaps.

  12. Using your chart, explain the pattern you see in Column A.

  13. Using your chart, explain the relationship between the numbers in Column A and Column B.

  14. Using your chart, describe the pattern you found in Column E.

  15. Explain how you found your answer to the 150-sided figure. How do you know that your answer is correct?

  16. Tesselation A tesselation is a pair of shapes with no gaps. This tessalation is made out of hexagons. Tesselation!!!!!!!
