The document discusses symmetry in nature, architecture, and art. It defines symmetry as a spatial relationship where one half of a shape is the mirror image of the other half. There are different types of symmetrical lines including horizontal, vertical, and diagonal. Symmetry can be classified as axial or radial depending on whether equal elements are equidistant from a central axis or point.

54. AXIAL SYMMETRY

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.

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.

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.

62. RADIAL SYMMETRY

63. RADIAL SYMMETRY

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.

66. GEOMETRIC SYMMETRY

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.

69. APPARENT SYMMETRY

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.
