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.

1. Opposite sides are equal 2. it is a parallelogram 3. all 4 angles (at vertices) are 900 4. diagonals are equal in length 5. diagonals bisect each other 6. triangles formed by a diagonal and 2 sides (opposite side for each triangle) are congruent 7. among the four triangles that are formed by the 2 diagonals, the vertically opposite triangles are congruent 8. if length=breadth, then the rectangle is a square 9. perimeter of the rectangle = 2 * ( length + breadth) 10. area of rectangle = length * breadth
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.
True.
Two congruent triangles.
It is helpful (not help full) because the two triangles formed by either diagonal are congruent.
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.

There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
how many triangles are formed when any parallelogram and it diagonals are drawn
a squished rectangle
Suppose that the parallelogram is a rhombus (a parallelogram with equal sides). If we draw the diagonals, isosceles triangles are formed (where the median is also an angle bisector and perpendicular to the base). Since the diagonals of a parallelogram bisect each other, and the diagonals don't bisect the vertex angles where they are drawn, then the parallelogram is not a rhombus.
