Any 2 congruent triangles joined together will form a 4 sided quadrilateral
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
Rhombus
A square
The reguar polygons are triangles, quadrilaterals and hexagons.

They make four triangles, not a triangle.
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.
No because all triangles have only 3 sides whereas quadrilaterals have 4 sides.

No, they do not.
Quadrilaterals, which have 4 sides, are not the same as triangles which have 3 sides. Some similarity exists in that both are geometrical figures.
They are both polygons.
In general, no.
Rhombus
Yes
Join the 6 triangles like pizza slices
