Rotate a Figure about a Point on the Figure.
(A). In the applet below is a right isosceles triangle. Perform the following operations:
What would it look like when you rotate the triangle 4 times around B:
(1). through 90 degrees clockwise?
(2). through180 degrees clockwise?
(3). through 270 degrees clockwise?
(B). In the applet below is a right isosceles triangle. Perform the following operations:
Rotate a Line Segment about a Point.
(A). In the applet below is a line segment CD. Perform the following operations:
Rotate a Line Segment about a Point.
(1). What is the image of A?
(2). What happens when you rotate a segment 180 degrees?
Describe a sequence of transformations that takes to
.
Here are two line segments:
Is it possible to rotate one line segment to the other? If so, find the center of such a rotation. If not, explain why not.
Here is a diagram built with three different rigid transformations of triangle ABC.
(1). Describe a rigid transformation that takes triangle ABC to triangle CDE.
(2). Describe a rigid transformation that takes triangle ABC to triangle EFG.
(3). Describe a rigid transformation that takes triangle ABC to triangle GHA.
