Study Notes
Area of Triangles
- The area of triangle LMN is 4 square units.
- Triangle QRS has an area of 7 square units.
- Triangle ABC with vertices A(1, 1), B(4, 0), and C(3, 5) also has an area of 7 square units.
- Triangle ABC with vertices A(0, 0), B(3, 4), and C(3, 2) has an area of 3 square units.
- Triangle GHJ has an area of 6 square units.
- The expression for finding the area of triangle RST is derived from the formula: (8 - 1/2) (10 + 12 + 16).
Area of Parallelograms
- The area of parallelogram ABCD, defined by points A(3, 6), D(2, 2), B(5, 6), C(5, 1), is 13 square units.
- To find the area, a rectangle should be drawn with dimensions of 4 units by 4 units.
- The base of parallelogram ABCD measures approximately 8.6 units, with a corresponding height of about 4.8 units.
- For parallelogram RSTU, if line segment RU is the base, the corresponding height is approximately 5.4 units.
- The areas of parallelogram ABCD and parallelogram EFGH are equal.
Additional Area Considerations
- Payton combines two shapes to create a house, resulting in a total area of 21 square units.
- When working with triangles, if line segment BC is considered the base, the corresponding height is 1.6 units.
