Study Notes
Area of Geometric Shapes
- The formula to calculate the area of a triangle is:
A = (b × h) / 2, wherebis the base andhis the height of the triangle. - The formula to calculate the area of a parallelogram is:
A = b × h, wherebis the base andhis 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 asm = (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.
