No, not every triangle is half of a rectangle. A rectangle has four sides and four right angles, while a triangle has three sides and three angles. The area of a triangle is not necessarily half of the area of a rectangle with the same base and height. Triangles and rectangles are different geometric shapes with distinct properties.

No. Although the area of every triangle is equal to half the area with the same base and height, only right angled triangles are half a rectangle.
Any kind of triangle can be made in a rectangle.
Could a triangle and a rectangle ever be congruent? explain
The term "rectangle method" is used in different ways in math, but I will guess that your question is related to finding areas on a Geoboard. A Geoboard has a grid of pegs; you can make outlines of figures by stretching elastic bands around the pegs. If your figure is a triangle, you can find it's area by making the smallest rectangle which will enclose the triangle (The rectangle should have vertical and horizontal sides). The area of the rectangle can be found easily by multiplying the length by the width. The area of the triangle is half of the area of the rectangle.
Never. A triangle has 3 sides, while rectangle has 4 sides.No
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
