Yes, all circles are similer, they all have 1 line, all the same shape, any quarter of a circle will always be 25%, but it the line is bigger they still have differances and similarities, e.g a circle can have a radius of 25cm while another can have a radius of 93984389569349billion miles

What shape is always similar?
Squares and circles are always similar.
Are circles similar or congruent?
Similar, in most instances. All their interior angles add to 360 (without exception), however, the measure of the diameter, perimeter (etc) could be different.
Do all circles have a diameter?
yes
What are congruent circles?
Circles that have congruent radii. Congruent=coinciding at all points when superimposed (http://dictionary.reference.com/browse/congruent)
Are all circles congurent?
No, they are all similar but, since the radii can differ, they need not be congruent.Two objects are congruent if they have the same dimensions and shape. Very loosely, you can think of it as meaning 'equal', but it has a very precise meaning that you should understand completely, especially for complex shapes such as polygons.
Why does Pi work for all circles?
Because all circles are similar.
Are all circles congruent?
No. There are big ones, medium ones, and little bitty ones.But all circles are similar.
Which figures are always similar in geometry?
Circles and all regular polygons.
Are circles sometimes never or always similar?
Circles are congruent when they have the same radius and they are similar when their radii are different in lengths.
Are ovals and circles similar?
Yes. Both circles and ovals have no sides.
What shape is always similar?
Squares and circles are always similar.
Are circles always similar?
No They Are Not * * * * * Yes, they are.
Is it true that circle are congruent?
All circles are similar, they all are the same shape, regardless of size. Only if they have equal diameters, would they be congruent.
If Two different circles have same circumference?
Then they are similar.
Are circles similar or congruent?
Similar, in most instances. All their interior angles add to 360 (without exception), however, the measure of the diameter, perimeter (etc) could be different.
Are all ellipses circles?
Ellipses are not circles.
All points on the surface of earth that have latitude circles that are not zero are known as what circles?
Small circles
