How is the triangle formula derived from the area of rectangles?
The area of a triangle is expressed using the formula A=(1/2)(bh) Where A is area Where B is length of the base of the triangle. Where H is the height of the triangle. The area of a rectangle is A=BH, Where B is the length of the base of the rectangle. Where H is the height of the rectangle. Because a triangle, essentially, is a half of a rectangle, you find the area of the whole rectangle that the triangle comes from, then divide that in half.
How do you make a rectangle with triangle and square?
Put the two bases of the triangle together. To form a square. Place the squares side by side to form a rectangle
How could you use the formula for area of a rectangle to find the formula for the area of a triangle?
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.
Teach a child area of triangle without formula?
You will have to use a formula, but this can easily be derived for the special case of a right triangle. If you divide a rectangle by a diagonal, you divide it into two congruent triangles, therefore, the triangle has half the area of the rectangle, that is, 1/2 times base times height.
Is a rectangle a triangle?
No, a triangle has 3 sides, a rectangle has 4
