We can complete the sentence as:
One way to recognize a line of symmetry is to look for a line that divides the original image into congruent parts.
What is symmetry?
Symmetry means that when one shape is moved, rotated, or flipped, it looks precisely like the other form.
What are the different types of symmetry?
The different types of symmetry are as follows:-
- Line symmetry: A line divides the image into two parts acting as a mirror between them and thus dividing the image into congruent parts.
- Point symmetry: When an image, rotates upon a certain point for 180° and gives the same image.
- Rotational symmetry: When an image, rotating upon a certain point for any angle less than 360°, gives the same image.
How to solve the question?
In the question, we are asked for one way to recognize a line of symmetry.
From our above discussion, we know that in line symmetry, a line divides the image into two parts acting as a mirror between them and thus dividing the image into congruent parts.
Thus, we can complete the sentence as:
One way to recognize a line of symmetry is to look for a line that divides the original image into congruent parts.
