TOPIC: GEOMETRIC TRANSFORMATIONS
VALUE: Respect encourages communication and understanding.
week 3
Action of moving something with the same shape and the same orientation
Translation
Action of turning something with the same shape around a fixed point in a circular motion
Rotation
Interactive game: Light bothttps://www.minijuegos.com/juego/light-bot
Help the robot to get to the positions 1, 2 and 3, in order, indicating the instructions used. Rotate according the robot perspective.
Activity: Maze instructions
Use T. for Translation, and R. for Rotation.
* 3 T. down* 1 R. left * 5 T. right * 1 R. left * 2 T. up * 1 R. left * 2 T. left * Got number 1!

It can be done in an horizontal or vertical way. Always draw points in the corners of the squares, and count as many squares as the units indicated in the translation.

Recognize all vertexes of the figure, and translate them one by one according to the units of the translation. At the end, connect the new dots accordingly.
Translation of shapes
Practice the translation of points in a plane of reference

STEP 1: Draw a triangle with vertexes A, B and C, and draw a fixed point P.
STEP BY STEP
STEP 2: Draw a line from point P to point A.
STEP BY STEP
STEP 3: Place your protractor centered in point P, and in direction to point A.
STEP BY STEP
STEP 4: Draw a little point/line at the indicated angle (70°), measured anticlockwise.
STEP BY STEP
STEP 5: Remove the protractor and connect the point P with the point/line drawn before.
STEP BY STEP
STEP 6: Use your compass to connect the point A with the line you just drew.
