Learning Objective
I can calculate the area of various two-dimensional shapes, including triangles, quadrilaterals, and circles.
- 1
The area of a triangle can be found using the formula ½ * base * height, where the height is the perpendicular distance from the base to the opposite vertex.
- 2
The area of a parallelogram is calculated by multiplying the base by the height, ensuring the height is measured straight up and down, not along the slant.
- 3
The area of a trapezoid is found using the formula ½ * (base1 + base2) * height, where base1 and base2 are the lengths of the parallel sides and the height is the perpendicular distance between them.
