TRANSFORMATIONS
|
MA.C.2.2.1 understands the
concepts of spatial relationships, symmetry, reflections, congruency,
and similarity.
MA.C.2.2.2 predicts,
illustrates, and verifies which figures could result from a flip, slide,
or turn of a given figure.
MA.C.3.2.2 identifies and plots
positive ordered pairs (whole numbers) in a rectangular coordinate
system (graph)

Vocabulary:
Flip: a transformation that produces the mirror image of a
geometric figure. Also called a reflection.
Rotation: a transformation of a figure by turning it about a
center point or axis. the amount of rotation is usually expressed in the
number of degrees (e.g., a 90 degrees rotation). Also called a Turn.
Slide: to move along in constant contact with the surface in a
vertical, horizontal, or diagonal direction. Also called a Translation.
Using graph paper:
- Build a Cartesian Plane and draw the
above shape.
- Label the points and write all the
ordered pairs corresponding to each one of the vertices of this
pentagon.
- Flip the shape southwards over the
x-axis.
- Write the new ordered pairs of the
place where the pentagon ended up.
