Understanding Perimeter and Area of Triangles
The area of a triangle is always calculated using the formula 1/2 × base × height, regardless of whether it is a right, scalene, isosceles, or equilateral triangle. Perimeter and area have practical applications, such as determining the...

Calculating the Area of a Triangle
To determine the area of a triangle, you use the formula: Area = 1/2 × Base × Height. This formula works because a triangle is essentially half of a rectangle or square. By identifying the base (the bottom side) and the height (the...
