Is the the semi-circles of two congruent circles always congruent?
Yes.
Are circles in the same plane and having the same center congruent circles?
Yes, it is. Circles that are in the same plane and having the same center are called congruent circles.
In a dilation the image is always similar to its pre-image?
Yes, it is.
If two cylinders are similar and the ratio between the lengths of their edges is 4 3 what is the ratio of their volumes?
it depends whether the area of the circles ontop are the same (pie x diameter) if so, yes. if not, no. 64:27 .
What is required for two triangles to be similar?
If ll the angles of one triangle are the same as the angles of another triangle they are similar. Rotation is always allowed and mirroring often can be allowed.
What shape is always similar?
Squares and circles are always similar.
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.
Which figures are always similar in geometry?
Circles and all regular polygons.
Are two circles sometimes always or never similar to each other?
They can b different sizes
What method is valid for proving that two circle are similar?
Two circles are similar if they have the same shape, which is inherently true for all circles since they are defined by their constant ratio of circumference to diameter (π). A valid method to prove that two circles are similar is to show that they both have equal angles, which is always the case since all circles have angles of 360 degrees. Furthermore, similarity can be established by demonstrating that one circle can be transformed into the other by uniform scaling, which preserves the shape. Thus, all circles are similar regardless of their sizes.
Are all circles congruent?
No. There are big ones, medium ones, and little bitty ones.But all circles are similar.
Are all circles similar?
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
Are ovals and circles similar?
Yes. Both circles and ovals have no sides.
Why does Pi work for all circles?
Because all circles are similar.
What figures will always be similar to each other?
A square of identical shape but not size is similar. For example, a square is always a square, whether big or small. Or, a box with 4 sides with exactly the same top and bottom will be similar, but these similar or identical boxes can be tiny....or huge. A circle will be similar to other circles, but size could differ.
Is the the semi-circles of two congruent circles always congruent?
Yes.
Why are circles always congruent?
No. They can me different sizes. For a shape to be congruent, they need to me same size and same shape.
