  14. Time to think…. • A park is shaped like a pentagon. Each side is 41 meters long. What is the perimeter of the park?

  15. Time to think… • A park is shaped like a pentagon. Each side is 41 meters long. What is the perimeter of the park? • 205 meters

  16. Time to think… • How many lines of symmetry does this polygon have?

  17. Time to think… • How many lines of symmetry does this polygon have?

  18. Time to think… • fd 50 • rt 120 • fd 50 • rt 120 • fd 50 • rt 120 • What type of polygon do these commands form?

  19. Time to think… • fd 50 • rt 120 • fd 50 • rt 120 • fd 50 • rt 120 • What type of polygon do these commands form? Equilateral Triangle, Acute Triangle, Isosceles Triangle

  20. Time to think… Are these triangles congruent or similar and why?

  21. Time to think… • Are these triangles congruent or similar and why? Similar because their angles are the same and their sides are in proportion

  22. Time to think… • What type of angle is this?

  23. Time to think… • What type of angle is this? Obtuse… more than 90°

  24. Time to think… 75º Find the missing angle: ?

  25. Time to think… • The missing angle is 105º

  26. Time to think… • If a triangle has a 40º angle and a 70º angle, what is the third angle?

  27. Time to think… • If a triangle has a 40º angle and a 70º angle, what is the third angle? • The missing angle is 70º.

  28. Explain… • Why is a square a rectangle, but a rectangle not a square?

  29. Explain… • Why is a square a rectangle, but a rectangle not a square? • A square is a rectangle because it has two pairs of congruent sides, two pairs of parallel sides, and four right angles. A rectangle is not a square because it does not have all 4 sides congruent.

  30. Time to think… • Solve this riddle: • I have two pairs of parallel sides. • I have no right angles • All of my sides are congruent to each other. • What am I?

  31. Time to think… • Solve this riddle: • I have two pairs of parallel sides. • I have no right angles • All of my sides are congruent to each other. • What am I? Rhombus
