Study Notes
Grade 6 Mathematics: Triangles, Quadrilaterals, and Polygons
- Triangle Definitions: Triangles are polygons with three sides and three angles. The sum of the interior angles of any triangle is 180 degrees.
Types of Trianglesv
-
By Sides:
- Equilateral: All three sides are equal in length.
- Isosceles: Two sides are equal in length.
- Scalene: All three sides have different lengths.
-
By Angles:
- Acute: All three angles are acute (less than 90 degrees).
- Right: One angle is a right angle (90 degrees).
- Obtuse: One angle is obtuse (greater than 90 degrees).
Area of a Triangle
- Area = (1/2) * base * height
Perimeter of Quadrilaterals
- Perimeter = sum of all side lengths
Calculating Polygon Areas
- The area of a polygon depends on its specific shape. Simple shapes such as rectangles, parallelograms, and triangles can be used to determine the area of more complex shapes.
