Figure that are congruent are shapes are the same size and shape. So when two formed congruent triangles are both together they fit just right.
Add them together!
If they are the same shapes but differ only in size, then they are SIMILAR shapes. Otherwise, they are simply different shapes.
trapizium
A triangular pyramid (tetrahedron) can be formed by joining two triangular shapes together along one of their edges. This configuration results in a shape that has three triangular faces, two edges, and one vertex, which is the point where the two triangular shapes meet.
When two shapes are joined together, it is called a composite shape.
4 rectangles / Correction: two triangles.

Two or more words put together to create a single complex idea could be called a phrasal compound.
