Yes. They can form a kite.
2 triangles together and a parallelogram is a quadrilateral that has 2 sets of equal sides. ☺
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.
When you put two acute triangles together, you can create various shapes depending on how they are arranged. For example, if you align them at a common vertex, you can form a larger triangle or even a quadrilateral. If placed base to base, they can create a parallelogram or a kite shape. The specific outcome will depend on the angles and sides of the triangles used.
They will form a 4 sided quadrilateral if the triangles are the same sizes.
This result follows from the theorem that the sum of the angles of a triangle is 180 degrees. Drawing a diagonal in the quadrilateral splits it into two triangles and the angles of the triangles together combine to form the angles of the quadrilateral.

If they are congruent right angle triangles then just join them together side by side to form a parallelogram.
Two scalene right triangles that are congruent, that is, that have identical size and shape, if joined together to form a quadrilateral, will form a rectangle.
Any 2 congruent triangles joined together will form a 4 sided quadrilateral
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.

I can use it when lines are joined together
