What is Area of a Triangle?
The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it. It is applicable to all types of triangles, whether it is scalene, isosceles or equilateral. To be noted, the base and height of the triangle are perpendicular to each other. The unit of area is measured in square units (m2, cm2).

How to find area of a triangle with 2 sides?
In a triangle, when two sides and the included angle is given, then the area of the triangle is half the product of the two sides and sine of the included angle. For example, In ∆ABC, when sides 'b' and 'c' and included angle A is known, the area of the triangle is calculated with the help of the formula: 1/2 × b × c × sin (A). For a detailed explanation refer to the area of the triangle with 2 Sides and included angle (SAS).
How to find the semi perimeter of a triangle?
The first step is to find the semi perimeter (half perimeter) of the given triangle by adding all three sides and dividing it by 2. The next step is to apply the value of the semi-perimeter of the triangle in the main formula called “Heron’s Formula”. Consider the triangle ABC with side lengths a, b, and c.
What is the area of a triangle?
Area of Triangle. The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h. This formula is applicable to all types of triangles, whether it is a scalene triangle, ...
How many sides are there in an isosceles triangle?

How to find the area of an equilateral triangle?
To calculate the area of the equilateral triangle, we need to know the measurement of its sides.
What is a triangle based on?
Triangles can be classified based on their angles as acute, obtuse, or right triangles. They can be scalene, isosceles, or equilateral when classified based on their sides.
What is an area?
The space that is occupied by a flat shape or the surface of an object. The standard unit of measurement is mostly either ㎡ or cm2. We are going to discuss the Area of triangles here.
How to find the area of an equilateral triangle?
The triangles in which the length of all the sides are equal are called equilateral triangles. In order to find the area of an equilateral triangle, we need to know the formula and since the only information that is always given to us in equilateral triangles is the measurement of the sides of the triangle. The formula for finding the area of the equilateral triangle is 34a2. The formula can be written as Area of the equilateral triangle = 0.433 a2. Here, a means the sides of the equilateral triangles.
What is the formula for finding the area of an isosceles triangle?
The triangle which has length of two sides equal is called an isosceles triangle. The formula for finding the area of an isosceles triangle is 12bh. It is done in the same way as of the right angle triangle. First we have to find the height which in the above mentioned example was 16 cm. However in finding the area of an isosceles triangle the base will remain 24 cm without dividing it by half.
What is the most powerful geometry?
Triangle is the most powerful geometry, which is a closed two-dimensional shape having three (3) sides. There are different types of triangles based on sides and based on angles. There are three different types of triangles based on sides; Equilateral, Isosceles, and Scalene. There are three different types of triangles based on angles; Right, Acute and Obtuse.
How to find the height of a triangle?
In this triangle, sometimes height is given, but often one has to find out the height by using Pythagoras theorem, that is a2+b2= c2 showing that the square of the longest side “c” is equal to the sum of the squares of the other two sides, here a, b and c are sides of the triangle. However, since, in order to find the height, we will draw the line, which will make the base of the triangle half. Area of a right-angled triangle = 12bh.
What is the area of a right angled triangle?
Area of a right-angled triangle = 12bh.
What is the perimeter of a triangle?
The perimeter of a triangle is the sum of all its three sides.
How to find area of a triangle?
Area of a triangle: The area of a triangle is calculated using the formula {eq}frac {1} {2}cdot {b}cdot {h} {/eq} where b is the base of the triangle and h is the height of the triangle.

5. For a given equilateral triangle, area = ¼√3 a².
What is the law of 90 degree angles?
they all have one 90 degree angle. the law A = 1/2 ab sin C can be used when you have the two shorter sides of a triangle, but not the longest side - a and b are the shorter sides, while C is the angle opposite to c, the longest side.
How to find area of two sides?
if you have two sides, and the angle opposite to the side you don’t know, then you can apply this rule straight away. multiply the two sides a and b, multiply that by the sine of the angle opposite to c, halve the result, and you have your area!
