Fill in the blanks using the correct word given in brackets: All circles are _______. (congruent/similar)
Explain why a circle is similar
Circles are round shaped 2D figures which can vary in size but never in shape.
So, the circles are similar.
A circle cannot be congruent as it is not compulsory that the size or radius of two or more circles will always be the same.
Hence, all circles are similar.
