Is the straight line where the radius is located the axis of symmetry of the circle?

The axis of symmetry of the circle is the line where the diameter is located, and the line where the radius is the axis of symmetry of the circle is right.

Any diameter of a circle is its own axis of symmetry, and the radius is of course counted.

Straight line, straight line! But there is no relationship note. I really don't know how to do that.

If the radius isn't the circle here, you're wrong.

It seems a bit far-fetched.

The axis of symmetry is a straight line, not a segment. The correct expression should be: the straight line where the diameter of the circle is located is the axis of symmetry of the circle.

Axis of symmetry: If folded in half along a straight line, and the two parts of the fold are completely overlapped, then such a figure beam is called an axisymmetric figure, and this straight line is called the axis of symmetry of this figure. The axis of symmetry is definitely a dotted line!

The circle is axisymmetric, and the straight line with the diameter (the straight line passing through the center of the circle in the same plane) is the starving axis of symmetry of the circle, and the circle has an infinite number of axes of symmetry.

A straight line in mathematics has no endpoints at either end, can extend infinitely to both ends, and is not measurable in length.

According to the meaning of the axisymmetric figure, it can be seen that the straight line where the radius is located is the symmetry axis of the circle, which is correct

So the answer is:

Summary. Correctly, the circle is not only axisymmetric but also centrally symmetrical. There are countless diameters of a circle, all of which can be axes of symmetry of a circle.

A circle is an axisymmetric figure with an infinite number of axes of symmetry, and its axis of symmetry is the diameter of the circle. Is this statement correct?

Correctly, the circle is not only axisymmetric but also centrally symmetrical. There are countless diameters of a circle, all of which can be axes of symmetry of a circle.

Have a great day.

From the analysis, it can be seen that the radius of the circle is its axis of symmetry, and the argument is mistaken for the reason that the straight line where any diameter is located is the axis of symmetry of the circle;

Therefore, the answer is: , the straight line where the diameter of the key is located is the axis of symmetry of the circle

Fold the circle in half along the straight line with a diameter along any volvu, and the two parts after the fold can completely coincide, then the circle is an axisymmetric figure, and the straight line where each diameter is located is a lack of its symmetrical axis;

So the answer is:

According to the meaning of the axisymmetric figure, it can be seen that the straight line where any radius of a circle is located is its symmetry.

So the answer is:

This is the right answer reference.

The circle is an axisymmetric figure, and the straight line where any diameter of the circle is located is the symmetry axis of the circle Test point: the understanding of the circle and pi

Analysis: According to the meaning of axisymmetric graphs: if a figure is folded in half along a straight line, and the parts on both sides of the straight line can be completely overlapped, then the figure is called an axisymmetric graph; It can be known:

The circle is axisymmetric, and the straight line where any diameter of the circle is located is the axis of symmetry of the circle; And then you can answer it

Answer: Solution: The circle is axisymmetric figure, and the straight line where any diameter of the circle is located is the symmetry axis of the circle;

So the answer is: axisymmetry, diameter

Comments: The knowledge points used to answer this question: (1) the meaning of axisymmetric figures; (2) Characteristics of circles

That's right. Any diameter on the circle, through one of the points as a perpendicular line, intersecting at two points, by the perpendicular diameter theorem, know that the distance from these two points to the diameter is equal, the same can be taken on the diameter of any other point, so that by the definition of axis symmetry, the diameter of the straight line is the axis of symmetry of the circle.

That's right. A circular pattern is an axisymmetric figure and is also a center-symmetrical figure.

The axis of symmetry of a circle is the straight line where the diameter of the circle is located, and there are countless axes of symmetry in this way.

Wrong. I also encountered this problem, and the elementary school teacher's reply was "the axis of symmetry is a dotted line". I can't accept this answer, because the dotted line is not geometry.

Moreover, the definition of axisymmetric graphs clearly states that the axis of symmetry is a straight line. Just draw a dotted line. However, I still think this question is wrong, and the constraint of "on the same plane" should be added.

That's right. Any straight line passing through the center of the circle is the axis of symmetry of the circle.

The straight line through the center of the circle is the straight line where the diameter (radius) segment of the circle is located, and any diameter of the circle is its axis of symmetry.

No, does the axis of symmetry pass through the circumference?
