Divide the rectangle in half, so you have two squares. Then cut each of these squares in half by drawing a straight line from the top left hand corner to the bottom right hand corner. Then you'll have four right angle triangles.

A rectangle, divided in half need not give a square. Try it with an A4 sheet of paper.
A much simpler answer is to draw the two diagonals.

The length and width of a rectangle are 8 inches and 4 inches respectively What would be the area of one of the triangles formed from drawing a diagonal in the rectangle?
A=l*w A=8*4 A=32 diagonal cuts the rectangle into two congruent triangles. 32/2 = 16
If a rectangle has a perimeter of 14 meters and a diagnol of 5 meters what is the area of the rectangle?
A rectangle must have four right angles and parallel sides. Therefore, you can divide the rectangle into two equal right angle triangles along the diagonal. As the perimeter is the sum of all of the sides of the triangles that aren't a hypotenuse, each of one of the triangles' legs length would add up to to half the perimeter of the rectangle i.e. 7. The length of the hypotenuse is 5. With basic trigonometry you should recognise that this is a pythagorean triple, or in otherwords the hypotenuse is 5 and the lengths of the 'legs' are 3 and 4 Now that you now know the lengths of the legs of the right angle triangles, and the legs correspond with the sides of the rectangles, you can now calculate the area: A = 4*3 = 12 m2
Can you show four identical right triangles in a rhombus?
Yes, draw the two diagonals. This will divide the rhombus into 4 identical triangles.

If you divide a 4 in by 8 in rectangle from corner to corner what new shape do you get?
You get two congruent right triangles when you divide a rectangle diagonally. (This is one way to show that the area of each of those triangles is 1/2*base*height. Rectangle area = (4 in)(8 in) = 32 in2. Triangle area = (1/2)(4 in)(8 in) = 16 in2.)

How do you divide a triangle into 4 equal parts?
Find the midpoint of each side. Draw lines between them. You get 4 identical triangles, similar to the original.
What has 4 right triangles?
A square and a rectangle
How do you make a parallelogram that is not a square from 4 identical isosceles right triangles?
Two isosceles right triangles, if joined hypotenuse-to-hypotenuse will make a square. Two squares, sided by side, make a rectangle which is a parallelogram, and not a square.
