Question

lesson 2 glossary terms image corresponding clockwise counterclockwise reflection rotation translation 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? b. which pair of cards shows a shape and its image after a reflection? 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.

Explanation:

Step1: Analyze rotation in Problem 1

A rotation is a transformation that turns a shape around a fixed - point. By observing the shapes on the cards, we can see that the shape on card 3 and card 5 are the same shape with one being a rotated version of the other.

Step2: Analyze reflection in Problem 1

A reflection is a transformation that flips a shape across a line of reflection. The shape on card 2 and card 6 are related by a reflection as they are mirror - images of each other.

Step3: Analyze movement in Problem 2

From frame 1 to frame 2, the shape moves up. From frame 2 to frame 3, the shape moves diagonally up and to the right. From frame 3 to frame 4, the shape moves down. From frame 4 to frame 5, the shape moves diagonally down and to the right.

Answer:

a. 3 and 5
b. 2 and 6
Problem 2: From frame 1 to 2: moves up; From frame 2 to 3: moves diagonally up and right; From frame 3 to 4: moves down; From frame 4 to 5: moves diagonally down and right
