Does Figure A show a flip of Figure B? Write yes or no.

Question 1.
Math in Focus Grade 3 Chapter 18 Practice 2 Answer Key Congruent Figures 1
Answer: No
Explanation:
A flip is also called a reflection,
which rotates an object end over end.
So, A and B are not flip.

Question 2.

Answer: Yes
Explanation:
A flip is also called a reflection,
which rotates an object end over end.
So, A and B are flip. and figure B is flip of figure A

Does Figure C show a slide of Figure D? Write yes or no.

Question 3.
Math in Focus Grade 3 Chapter 18 Practice 2 Answer Key Congruent Figures 3
Answer: YES
Explanation:
Slides are the simplest transformation–just moving something from one place to another.  In primary grades, we usually describe a slide using relative position words, such as “slide down” or “slide to the right and down”
So, figure C slides right to form figure D.

Question 4.
Math in Focus Grade 3 Chapter 18 Practice 2 Answer Key Congruent Figures 4
Answer: YES
Explanation:
Slides are the simplest transformation–just moving something from one place to another.  In primary grades, we usually describe a slide using relative position words, such as “slide down” or “slide to the right and down”
So, figure C slides right to form figure D.

Does Figure E show a turn of Figure F? Write yes or no.

Question 5.

Answer: Yes
Explanation:
A turn or a rotation describes the motion of turning a shape as if it were drawn on a piece of paper.
The usual primary-grades vocabulary is a “turn” and the usual middle-grades vocabulary is “rotation”.

Question 6.
Math in Focus Grade 3 Chapter 18 Practice 2 Answer Key Congruent Figures 6
Answer: YES
