![]() ![]() 3 Sides 1 Line 4 Sides 4 LinesĪll of their faces have one line of symmetry.Įquations need: Rx-axis (x,y) = (x, -y) Ry-axis (x,y) = (-x,y) Ry=x (x,y) = (y,x) Ry=-x (x,y) = (-y,-x) Pre-Image over line, find coordinates 3 Sides 3 Lines 4 Sides 2 Lines Line of Symmetry In a non regular polygon, one must just count. In a regular polygon, the number of lines of symmetry is equal to the number of side. Isometry – transformation which the two figures are congruent.Line of symmetry – a figure that can be mapped onto itself by a reflection in the line.Line of Reflection – the which acts like a mirror in a reflection.Reflection – an image over a line, that almost acts like a mirror. "EK Success Wavy Circle Large Punch." BGPayne Crafts.It can be mapped onto itself at 36 degrees. Real Life Application The top of Tweety’s bird cage has rotational symmetry. Rotate Tweety 110 degrees about point P, (9,4), so that he is in his cage. Help Tweety Tweety wants to go into his cage. An equilateral triangle can be mapped onto itself by 120 degreesĬenter of Rotation: (0,0) Angle of Rotation: 270° Vertices: A (-4,4,)Ě’ (4,4) B (-2,4) B’ (4,2) C (-2,2) C’ (2,2) D (-4,2)ĝ’ (2,4) A B A’ D’ B’ C’ C Dī A C Eĝ F Center of Rotation: Point F Angle of Rotation: 80 degrees.Rotational Symmetry: when a figure can be mapped onto itself by a clockwise rotation of 180 degrees or less.Center of Rotation: the fixed point of a rotation.Angle of Rotation: rays drawn from the center of rotation to a point and its image form an angle.Rotations A rotation is an isometry where shapes rotate around a fixed point in a circular motion, whether clockwise or counter clockwise Dilations – Sebastian QuianaSpongebob Table of Contents.Tessellations – Justin Fernandez Scooby Doo.Translations – Eric Spiniello Tom and Jerry.Cartoon Transformations By: Justin Fernandez, Fiona McClean, Sebastian Quiana, Eric Spiniello, and Wendy Star
