How many lines of symmetry does a circle have

Circles have an infinite amount of lines of symmetry. You can go on and on and on and never find a specific number of lines of symmetry. Circles are the only figures that have an infinite amount of lines of symmetry.

how many lines of symmetry does a circle have

A circle has infinite lines of symmetry

how to find total number of lines of symmetry

just do it as many times and many ways till you get all you need

I did not understand how the pentagon had symmetry that way can you help me please?

Yes, if you fold the pentagon over the dotted line, then the two pieces would match perfectly.

How many line of symmetry does a circle have?

A circle has infinite amount of lines maybe 20 or more

so the amount of sides there is in the shape is how much lines of symmetry there is in that shape

Symmetry is basically two sides of a shape that are the same. Imagine a triangle split in half. That would be symmetrical. Good luck and keep practicing!

how do you solve decomposing angles when there is no sign of solving it. it is impossible when you have to subtract the numbers and then the answer is wrong, i never get the decomposing angle questions right, i always get 0% in them. geometry is difficult. isn't it. i always try to solve the questions if they are not right, but it never is right and i never get them right even after having a second go at them.

Every body can make mistakes just keep trying

How much lines does a star have

Draw out a star and count them. For your normal 5-pointed star, you can draw a line of symmetry straight down the middle. You can also rotate the star so that the next point is on top, and draw a vertical line of symmetry for that. Keep going, and you end up with 5 lines of symmetry, one for each point.

Lesson 6: Line of symmetry

Symmetry review

Review symmetrical shapes and lines of symmetry. Then, try some practice problems.

Line of symmetry

A start color #1fab54, start text, l, i, n, e, space, o, f, space, s, y, m, m, e, t, r, y, end text, end color #1fab54 is a line where we can fold the image and have both halves match exactly.

Example:

When we divide the figure with Line start color #1fab54, A, end color #1fab54, the resulting two parts are mirror images of each other:

Line start color #1fab54, A, end color #1fab54 is a line of symmetry.

Symmetrical figures

Shapes are start color #aa87ff, start text, s, y, m, m, e, t, r, i, c, a, l, end text, end color #aa87ff if they have at least one start color #1fab54, start text, l, i, n, e, space, o, f, space, s, y, m, m, e, t, r, y, end text, end color #1fab54 on them.

Example:

This shape is start color #aa87ff, start text, s, y, m, m, e, t, r, i, c, a, l, end text, end color #aa87ff:

Because we can draw at least one start color #1fab54, start text, l, i, n, e, space, o, f, space, s, y, m, m, e, t, r, y, end text, end color #1fab54 on it:
