How do you find the area of a triangle with 3 coordinates?
How Do You Find the Area of a Triangle With 3 Coordinates? Area of triangle with 3 points is: A = (1/2) |x1 1 (y2 2 − y3 3 ) + x2 2 (y3 3 − y1 1 ) + x3 3 (y1 1 − y2 2 )|, where (x1 1 ,y1 1 ),(x2 2 ,y2 2 ), and (x3 3 ,y3 3 ) are the coordinates of vertices of triangle.
How do u find the area of a equilateral triangle?
In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.
What is the area of the triangle LMN?
4 square units
Therefore, the area of the triangle LMN = 4 square units.
How do you calculate the area of a triangle?
Area of Triangle. The area of a triangle is defined as the total space that is enclosed by any particular triangle. The basic formula to find the area of a given triangle is A = 1/2 × b × h, where b is the base and h is the height of the given triangle, whether it is scalene, isosceles or equilateral.
How do you find the perimeter of a triangle?
Remember the formula for finding the perimeter of a triangle. For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c. What this formula means in simpler terms is that to find the perimeter of a triangle, you just add together the lengths of each of its 3 sides.
What is the formula for perimeter of a triangle?
Perimeter of a triangle formula. The formula for the perimeter of a triangle T is T = side a + side b + side c, as seen in the figure below: However, given different sets of other values about a triangle, it is possible to calculate the perimeter in other ways.
What is the perimeter of a right angle triangle?
Perimeter of Right Triangle. A right triangle has a base(b), hypotenuse(h) and perpendicular(p) as its sides, By the pythagoras theorem, we know, h 2 = b 2 + p 2. Therefore, the Perimeter of a right angle triangle= b + p + h.
