Practice

Determine whether each figure has line symmetry. Write yes or no. Draw the line(s) of symmetry on the figures that have line symmetry.

Question 1.
McGraw Hill My Math Grade 4 Chapter 14 Lesson 10 Answer Key Draw Lines of Symmetry 1
Answer: Yes
McGraw-Hill-My-Math-Grade-4-Chapter-14-Lesson-10-Answer-Key-Draw-Lines-of-Symmetry-1
If a figure can be folded over a line so that one half of the figure matches the other half, it has line symmetry. The fold line indicating that a figure’s two halves match exactly is called Line of symmetry.
Here, in the above figure, we have 3 lines of symmetry as the given figure is an equilateral triangle. The line of symmetry is indicated using a black line in the figure.

Question 2.

If a figure can be folded over a line so that one half of the figure matches the other half, it has line symmetry. The fold line indicating that a figure’s two halves match exactly is called Line of symmetry.
Here, in the above figure, we have 1 line of symmetry. The line of symmetry is indicated using a black line in the figure.

Question 3.

Answer: Yes
McGraw-Hill-My-Math-Grade-4-Chapter-14-Lesson-10-Answer-Key-Draw-Lines-of-Symmetry-3
If a figure can be folded over a line so that one half of the figure matches the other half, it has line symmetry. The fold line indicating that a figure’s two halves match exactly is called Line of symmetry.
Here, in the above figure, we have 2 lines of symmetry. The line of symmetry is indicated using a black line in the figure.

Question 4.
McGraw Hill My Math Grade 4 Chapter 14 Lesson 10 Answer Key Draw Lines of Symmetry 4
Answer: No
If we fold the figure, the left and right side of the folded line is not symmetrical to each other, which implies this as an example of an asymmetrical figure.

Determine whether the dotted line is a line of symmetry for each figure. Write yes or no.

Question 5.
McGraw Hill My Math Grade 4 Chapter 14 Lesson 10 Answer Key Draw Lines of Symmetry 5
Answer: No
The dotted line here is not the line of symmetry. If you fold the figure along the dotted line as shown above, i.e. you fold a rectangle through its diagonal, the two halves of the folder part will not be in symmetry to each other.

Question 6.
McGraw Hill My Math Grade 4 Chapter 14 Lesson 10 Answer Key Draw Lines of Symmetry 6
Answer: Yes
The dotted line here indicated the line of symmetry. If you fold the figure along the dotted line as shown above, the two halves of the folded part are symmetrical to each other.

Draw the other half of each symmetrical shape.

Question 7.
McGraw Hill My Math Grade 4 Chapter 14 Lesson 10 Answer Key Draw Lines of Symmetry 7
Answer:
McGraw-Hill-My-Math-Grade-4-Chapter-14-Lesson-10-Answer-Key-Draw-Lines-of-Symmetry-7
The dotted line here indicated the line of symmetry. If you fold the figure along the dotted line as shown above, the two halves of the folded part are symmetrical to each other.

Question 8.
McGraw Hill My Math Grade 4 Chapter 14 Lesson 10 Answer Key Draw Lines of Symmetry 8
Answer:
McGraw-Hill-My-Math-Grade-4-Chapter-14-Lesson-10-Answer-Key-Draw-Lines-of-Symmetry-8
The dotted line here indicated the line of symmetry. If you fold the figure along the dotted line as shown above, the two halves of the folded part are symmetrical to each other.

McGraw Hill My Math Grade 4 Chapter 14 Lesson 10 Answer Key Draw Lines of Symmetry 9
(A) 3
(B) 1
(C) 2
(D) 0
Answer: B (1)
The above sign have one line of symmetry. If you fold the sign exactly half vertically, the two halves of the folded parts are in symmetry.
