The area of a triangle is fixed. What's the ratio between its base and its height? What is the corresponding height
If xy = K (x, y, K are all positive numbers)
What do you think is the relationship between X and y
It is obviously in inverse proportion
Then the triangle area must not be s = 1 / 2 * a * B
a. If B is high, of course, it is in inverse proportion
Is the area of a triangle out of proportion to its base? Explain why
Out of proportion
The area of a triangle is related to its base and height
It's not about the bottom one
When the height is one, the area of the triangle is proportional to the bottom of the triangle
What's the ratio between the length, area and width of a rectangle? And explain the reason
A rectangle has a certain length, area and width
Because: Area / width = length (certain)
The quotient is constant, and the other two quantities are in direct proportion
