Answer:
In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.
Step-by-step explanation:
Remember Generalization is like an inference.
You need to write a statement that is based on the given information about Anna's shapes.
_______________________________________________________
If we look at Anna's shapes we have 2 quadrilaterals and 1 triangle.
Then, the "following" shapes have the same properties meaning 2 quads and 1 triangle.
We can go straightforwardly by saying the shapes that Anna chose are 2 quadrilaterals and 1 triangle.
Parallel sides are only shown on 2 of the shapes (the square and the parallelogram).
There are 3 triangles: 1 right, 1 obtuse, and 1 equilateral or acute.

Here's my generalization:
If we look at the shapes that Anna chose, we can identify 2 quadrilaterals and 1 triangle. The following shapes don't belong with the ones she chose because there are 2 triangles (equilateral and one right triangle). Then, we have a square with 2 sets of parallel lines which the parallelogram has. The other quadrilateral doesn't have any parallel lines which can't be a trapezoid either. In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.
