Questions and Answers

What is the formula to calculate the area of a triangle?

The formula to calculate the area of a triangle is (1/2) * base * height.

What is the formula to calculate the area of a parallelogram?

The formula to calculate the area of a parallelogram is base * height.

How are the formulas to calculate the area of a triangle and a parallelogram related?

The formula to calculate the area of a parallelogram is derived from the formula to calculate the area of a triangle, by multiplying it by 2.

What is the concept of slope in mathematics?

Study Notes

Area of Geometric Shapes

The formula to calculate the area of a triangle is: A = (b × h) / 2, where b is the base and h is the height of the triangle.
The formula to calculate the area of a parallelogram is: A = b × h, where b is the base and h is the height of the parallelogram.
The formulas for calculating the area of a triangle and a parallelogram are related in that they both use the base and height of the shape, but the triangle's formula is halved.

Slope in Mathematics

The concept of slope represents the steepness of a line, indicating how quickly it rises or falls.
Slope is represented in mathematical notation as m, and is calculated as m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
The significance of slope in linear equations is that it determines the direction and steepness of the line, with a positive slope indicating a rising line, a negative slope indicating a falling line, and a slope of zero indicating a horizontal line.
