#### Transcript of TRANSFORMATIONS

Maisie Manthey Pd. 5 TRANSFORMATIONS Reflections ROTATIONS TRANSLATION DILATION A rotation is when you turn a figure around
a point. It can also be called a turn. A translation is when every point in a figure moves
the same distance in one or two directions within a
plane. It can also be called a slide A dilation changes the size of a figure, but not it's
shape. It may be an enlargement or a reduction. A reflection produces a mirror image of a
figure by flipping it over a line. It is also known as a flip. EX. a b c a c b How Reflections Work: Activities A reflection is almost like a translation, but the shape
isn't slid onto the other side, it is mirrored. Therefore
the points of the shape "change". a b c d b a d c example 2 example 2 how to: http://www.mangahigh.com/en_us/games/transtar http://www.kidsmathgamesonline.com/geometry/transformation.html IN-DEPTH DEFINITION: STILL CONFUSED? http://www.mathsisfun.com/geometry/reflection.html EX. Rotated: 180 degrees What Exactly Is A Rotation: A Rotation is a transformation that turns a figure about a fixed point. Rotation is also called as turn.
The fixed point around which a figure is rotated is called as center of rotation.
Still confused? Activities http://hoodamath.com/games/rotateandroll.php http://nlvm.usu.edu/en/nav/frames_asid_299_g_2_t_3.html This figure slides 7 units to the left and 3 units down What exactly is a translation Activities A translation is to move an item up, down, left, or right without rotating it. Still Confused? http://www.mathplayground.com/ShapeMods/ShapeMods.html http://www.sciencekids.co.nz/gamesactivities/math/transformation.html http://www.mathsonline.co.uk/nonmembers/gamesroom/transform/golftrans.html This triangle was dilated by a scale factor of two (enlarged) This Triangle Still Confused? Was dilated by a scale factor of 1/2 . Activities

Additional Info http://www.mathsisfun.com/geometry/resizing.html http://www.mathwarehouse.com/algebra/matrix/matrix-dilation.php WHAT EXACTLY IS A TRANSFORMATION A transformation changes the position of a point or figure on a coordinate plane Such as a ROTATION, TRANSLATION, REFLECTION or DILATION Which was all previously mentioned above Feel free to look back if still confused!
