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.
yes
Correct
Yes, since all the sides of a square are equal and the definition of an isosceles triangle is to have at least two congruent sides. The congruent triangles formed are 45-45-90 triangles, so the diagonal will be the longest side with the right angle formed where the two sides of the square meet.
Yes, all parallelograms can be split into two congruent triangles. This is achieved by drawing a diagonal line connecting two opposite vertices. This diagonal divides the parallelogram into two triangles that are congruent by the Side-Angle-Side (SAS) postulate, as they share a side (the diagonal), and the angles formed at the vertices are equal.
Two congruent triangles.
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.
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.

True.

Correct
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
It can be, or one big triangle and two small congruent ones, or ... There are infinitely many options.
