Let's break down the situation.

Parallelogram and Diagonals

Consider a parallelogram, which has two diagonals. These diagonals intersect at their midpoint, dividing the parallelogram into two triangles. In your example, you're asking what would happen if we used the other diagonal to divide the parallelogram into two triangles.

Area of a Parallelogram

The area of a parallelogram is given by the formula:

$\text{Area of Parallelogram} = \text{base} \times \text{height}$

where the base is the length of one side, and the height is the perpendicular distance between the parallel sides.

Dividing with the Diagonal

When we divide the parallelogram using one of its diagonals, we get two triangles. Since the diagonal divides the parallelogram into two equal parts (because the diagonal bisects the parallelogram), the area of each triangle is exactly half of the area of the parallelogram.

Thus, the area of each triangle is:

$\text{Area of each triangle} = \frac{1}{2} \times \text{Area of Parallelogram}$

If the Other Diagonal Were Used

If we used the other diagonal to divide the parallelogram into two triangles, the result would still be the same. Here's why:

• A diagonal divides a parallelogram into two triangles.
• The two triangles share the same base (which is the diagonal) and height (the perpendicular distance from the base to the opposite side).
• Both triangles still cover the entire area of the parallelogram, and thus, each triangle would have an area equal to half of the parallelogram's total area.

In conclusion, whether we use the first diagonal or the second diagonal, the area of each of the resulting triangles will always be half of the area of the parallelogram.

Key Point:

• The area of each triangle formed by any diagonal of the parallelogram will always be half of the area of the parallelogram.
