What shape will you always get when you combine a trapezoid pattern block and a triangle pattern block?

I'm trying to visually recall the sizes of pattern blocks.........

depending on which sides the two blocks share, one could get a larger triangle or a parallelogram

When you combine a trapezoid pattern block and a triangle pattern block, you would get a parallelogram shape. To create this shape, you need to align the trapezoid block and triangle block adjacent to each other with their corresponding sides. By doing so, the combination of the two blocks will form a parallelogram.

To determine the shape you will always get when you combine a trapezoid pattern block and a triangle pattern block, we first need to understand the characteristics of each shape.

A trapezoid is a quadrilateral with one pair of parallel sides. It has four sides, with the parallel sides being of different lengths. The other two sides, known as the non-parallel sides, are also of different lengths.

A triangle, on the other hand, is a polygon with three sides and three angles. All three sides of a triangle are connected by three vertices or points.

Now, to find the resulting shape when combining the trapezoid and triangle pattern blocks, the key is to identify the common edges that can be joined together.

If we join one of the parallel sides of the trapezoid with one side of the triangle, we will have two sides connected with one vertex at each end. This will result in a new shape, which is a quadrilateral. Specifically, it will be a quadrilateral with one pair of parallel sides (like the trapezoid), but with one extra vertex (due to the triangle), resulting in a more complex shape.

Therefore, the shape you will always get by combining a trapezoid pattern block and a triangle pattern block is a quadrilateral with one pair of parallel sides and one additional vertex.
