- Area of a Triangle
If you divide a rectangle into two equal parts by drawing any of its diagonals, each half of the rectangle is a right-angled triangle. See the diagram below. We can then use this to find the area of a triangle.
Area of a right-angled \( \scriptsize \Delta = \normalsize \frac {1}{2} \scriptsize \; \times \; base \; \times \; height \)
Example 8.5.1:
Calculate the area of the triangle with a base of 6 cm and a height of 4 cm
