10 rhombuses, 1 circle and 10 triangles
A concentric circle, non regular triangles phaps in non-linearplane as a side of the triangle is definitely an arc. a few non regular 4 sided figure looks like rhombi but not congruent to others.
Got polygons, as well as a circle and triangles?I'm too lazy to count...
Circle not round so is it a circle? Cannot see the other sides, only 2 sides of triangle and rhombus can be seen? Not definite
basically mean same shape and sizecongruent - 4 tests to define congruency similarity is a subset of congruency
