Question

practice problems: problem 1 each of the six cards shows a shape. a. which pair of cards shows a shape and its image after a rotation? 3 and 5 b. which pair of cards shows a shape and its image after a reflection? 2 and 6 problem 2 the five frames show a shapes different positions. describe how the shape moves to get from its position in each frame to the next. from frame 2 to 3 rotated 90° cw up and right, from frame 3 to 4 translates down, and from frame 4 to 5 flip down

Explanation:

Problem 1a:

Check each pair for rotation. Rotation is turning a shape around a point. Cards 3 and 5 show a shape and its rotated - version.

Problem 1b:

Check each pair for reflection. Reflection is flipping a shape over a line. Cards 2 and 6 show a shape and its reflected - version.

Problem 2:

Frame 1 to 2:

The shape moves up.

Frame 2 to 3:

The shape is rotated 90° clock - wise.

Frame 3 to 4:

The shape moves up and to the right.

Frame 4 to 5:

The shape is flipped down.

Answer:

a. 3 and 5
b. 2 and 6
Problem 2: From frame 1 to 2, moves up; from frame 2 to 3, rotated 90° clock - wise; from frame 3 to 4, moves up and right; from frame 4 to 5, flipped down.
