Lesson 6: Line of symmetry

# Identifying symmetrical figures

Lindsay identifies lines of symmetry on three shapes.

## Want to join the conversation?

• their is actually one of the lines that are not symmetrical; after Lindsay did the first line, but the second line isn't symmetrical because at aone shape piece wasn't the same as the other piece.
• It's only slightly off
• Isn't the rectangle supposed to have 4 lines of symmetry? I thought this because you can also draw a line from each corner of the rectangle.
• Try folding a rectangle from corner to corner
• how can i identify a line of symmetry on ANY regular polygon
• if when you cut it in half, two sides ate EQUAL to each other

• How many lines of symmetry does a circle have? How many lines of symmetry does an oval have?
• Circle has infinite lines of symmetry. Oval has two.
• what is symetry
(1 vote)
• Symmetry is when you split an object with a line of symmetry into two parts that are exactly similar. So, if I have a circle and draw a line of symmetry in its middle, I would be able to split the circle into two identical parts. Those identical parts are symmetry.
• What's the maximum number of symmetrical lines a shape can have?
• Think about a circle. It has an uncountable lines of symetry. A lot of other shapes as well.

If you need more help just tell me.

• a circle has no sides
• Yes.. a circle does not have sides. (in case you are a first grader.)
• Hey guys!

I hope you are doing well :-)

I'd love to send you a very strong paragraph which will boost your knowledge and can learn many new things.

There you go :-

“Being Proactive”

Being proactive means taking initiative and responsibility for one’s actions and decisions. It involves expecting problems, setting goals, and taking steps to prevent issues before they arise. A proactive person is always looking for ways to improve themselves and their situation, rather than waiting for things to happen.
Imagine a scenario for reference, you’re bored, don’t have anything to play with or spend time with. You could spend your delightful time by coming up with genius ideas. Which means, you can make your own fun by making new items, which will give you interest and eventually, you can spend your time instead of being bored. By being proactive, individuals can stay ahead of challenges, make better decisions, and create best opportunities for growth and success. It is a mindset that empowers individuals to take charge of their lives and achieve their inseparable goals soon. 😁 😄

Thank you very much for your consideration and time. Wish you good health, can’t wait to see you forward!

Bye, take care ♥ ❤️
• Mam,what does line of symmetry of line mean?
(1 vote)
• A line of symmetry is a line that you can draw across a shape and divide it into two mirror-images. That is to say, each half of the shape is the same, but looks like its been flipped from the other.
You can also think of a line of symmetry as a line that you can draw, that when you fold the shape over the line both edges would line up exactly, without one side overlapping the other anywhere.
