The formula for finding the area of a triangle is A = 1/2 * base * height. This means that you multiply the base of the triangle by its height and then divide that product by 2.
Based on the length of its sides, a triangle can be classified as equilateral, isosceles, or scalene. An equilateral triangle has three equal sides, an isosceles triangle has two equal sides, and a scalene triangle has no equal sides. To determine the type of triangle, you can measure the lengths of its sides with a ruler or use the Pythagorean theorem to compare the lengths.
No, you cannot find the area of a triangle with only the length of its sides. You also need to know the height of the triangle or the length of one of its angles. Without this information, it is not possible to accurately calculate the area.
A right triangle has one angle that measures 90 degrees, also known as a right angle. The other two angles can vary in measure depending on the lengths of the sides, but they will always add up to 90 degrees.
The area of a triangle is always positive because it is a measure of the amount of space enclosed by the triangle. It cannot have a negative value as it represents a physical quantity.
