Area (Triangle)
To find the area of a triangle, you generally need to know the length of the base and the height
To find the area of a triangle, you generally need to know the length of the base and the height. The formula for the area of a triangle is:
Area = (base * height) / 2
Here’s how you can calculate the area step by step:
1. Identify the base and height of the triangle. The base is the length of the bottom side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex.
2. Measure the length of the base. Let’s say it is 8 units.
3. Measure the height of the triangle, which is the perpendicular distance from the base to the opposite vertex. Let’s say it is 5 units.
4. Plug the values of the base and height into the formula:
Area = (8 * 5) / 2
Area = 40 / 2
Area = 20
The area of the triangle is 20 square units.
It is important to note that if you have a right-angled triangle and know the lengths of two sides that intersect at a right angle, you can also use the Pythagorean theorem to find the height. The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
