It can be, or one big triangle and two small congruent ones, or ... There are infinitely many options.
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
A kite is a quadrilateral with two distinct pairs of adjacent sides that are congruent. In terms of triangles, a kite can be formed by two congruent right triangles sharing a hypotenuse, or by two congruent isosceles triangles sharing a base. Additionally, a kite can also be formed by combining two congruent scalene triangles with a shared side.
pentagon
Let's draw the isosceles trapezoid ABCD, where AD ≅ BC, and mADC ≅ mBCD. If we draw the diagonals AC and BD of the trapezoid two congruent triangles are formed, ∆ ADC ≅ ∆ BDC (SAS Postulate: If two sides and the angle between them in one triangle are congruent to the corresponding parts in another triangle, then the triangles are congruent). Since these triangles are congruent, AC ≅ BD.
If one of the nine toothpicks is the common base of the two congruent isosceles triangles with sides formed by two toothpicks.
Two congruent triangles.
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.
If the triangles are congruent and you match the hypotenera the right way, you can get a rectangle. If the triangles are not congruent, you can't even necessarily get a quadrilateral.
A rhombus.
Four.
