1 Trapezoids can be formed by joining three Draw all shapes that
can be formed by
equilateral triangles of equal size. Draw all shapes joining the shape
that can be formed by joining three trapezoids at made with two
trapezoids and
their sides of equal length. (If one shape matches another trapezoid.
another after being flipped or rotated, the two
shapes are considered to be the same.)
