  34. 51. There are two kinds of symmetry
  35. 52. There are two kinds of symmetry Axial symmetry
  36. 53. There are two kinds of symmetry Axial symmetry Radial symmetry
  37. 54. AXIAL SYMMETRY
  38. 55. AXIAL SYMMETRY It appears when the equal elements in a figure are equidistant . They are at the same distance from the straight line called symmetry axis , but opposed.
  39. 56. AXIAL SYMMETRY It appears when the equal elements in a figure are equidistant . They are at the same distance from the straight line called symmetry axis , but opposed.
  40. 57. AXIAL SYMMETRY It appears when the equal elements in a figure are equidistant . They are at the same distance from the straight line called symmetry axis , but opposed.
  41. 58. AXIAL SYMMETRY It appears when the equal elements in a figure are equidistant . They are at the same distance from the straight line called symmetry axis , but opposed.
  42. 59. AXIAL SYMMETRY It appears when the equal elements in a figure are equidistant . They are at the same distance from the straight line called symmetry axis , but opposed.
  43. 60. AXIAL SYMMETRY It appears when the equal elements in a figure are equidistant . They are at the same distance from the straight line called symmetry axis , but opposed.
  44. 62. RADIAL SYMMETRY
  45. 63. RADIAL SYMMETRY
  46. 64. RADIAL SYMMETRY It appears when each point of a figure corresponds with another point in the same figure. The opposing points are on the same line, opposed, and at the same distance of another point called centre of symmetry.
  47. 66. GEOMETRIC SYMMETRY
  48. 67. GEOMETRIC SYMMETRY The main feature of geometric symmetry is the accuracy in the drawing of the points that are equidistant from the axis (axial figures) or symmetry centre (radial figures). To draw figures with geometric symmetry we use a square, a set square, a ruler and a pair of compasses.
  49. 69. APPARENT SYMMETRY
  50. 70. APPARENT SYMMETRY The main feature of geometric symmetry is the accuracy in the drawing of the points that are equidistant from the axis (axial figures) or symmetry centre (radial figures). To draw figures with geometric symmetry we use a square, a set square, a ruler and a pair of compasses.
