If you draw a diagonal in a rectangle you get two equal triangles, each half the area of the rectangle.
Area of rectangle is base x height, so half of that is ½ x base x height. QED
A rectangle consists of two pairs of parallel lines which means that it is a parallelogram. However, the angles of a parallelogram need not be right angles, so all parallelograms are not right angles.
Could a traingle and a rectangle ever be congruent? Explain.
no because it is not the same shape or size.
I think if it were to be a triangle that it would be six on each

No. You cannot conclude anything about a shape which is not visible.
no because it is not the same shape or size.
is a trapezoid a parallelogram

All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
I won't explain it in depth but the simple answer is because if you take and identical right triangle then you can arrange them to make a rectangle. I've attached a link to an animation showing it rearranging a triangle to show the relationship.
explain what the triangle trade was
A square is a rectangle because a square has 2 parallel sides and so does a rectangle .
A trapezoid is not a parallelogram because they both have different properties but they are both 4 sided quadrilaterals
