Can you explain why the area of a triangle is 1 half base height while the area rectangle or a parallelogram is expressed as base height?
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
Why is the area of the triangle half the base times the height?
Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that.
A triangle is within a rectangle. how to find the ratio of the area of triangle to the rectangle?
Sounds like the triangle is spread out so that (the point is at the top of the rectangle) and (the base of the triangle is the same as the base of the rectangle).Base of rectangle = base of triangleHeight of rectangle = height of triangleWrite the formulas:Area of the rectangle = (base) times (height)Area of triangle = (one half of) (base) times (height)Can you see the ratio now ?
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 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.

How are the formulas for area of a triangle and rectangle similar?
the area of a triangle is half of the base times the height the area of a triangle is half of the base times the height

Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that.

Is every triangle half of a rectangle?
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.
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.

How is finding the area of a triangle different from finding the area of a rectangle?
the area of a triangle is base times height times one half and rectangle is length times width
How can you show that the area of a triangle half the area of the rectangle with the same base and height?
Draw a diagonal line across the rectangle. The resulting two right triangles will each have identical areas half that of the rectangle. The area of the rectangle is its height x base, and the area of each of the two triangles is 1/2 of its height x base.
How do you find the area of a 45-45-90 triangle?
The base times the height divided by two. Imagine a right triangle is half of a rectangle. The area will also be half.
Can you find the area of ANY triangle by usingbase times height divided by 2?
Yes because the area of a rectangle is base times height and every triangle is half a square.
How you find the height of a triangle if only you have the area and the base?
YOu divide the Base by half, and then DIvide the area by half of the base to get the height.
