What is the area of a triangle with vertices at (0 -2) (8 -2) (9 1)?
If the vertices are at (0, -2) (8, -2) and (9, 1) on the Cartesian plane plane then by using the distance formulae and trigonometry the area of the triangle works out as 12 square units.
What is the formula of triangle area?
There are different formulae, depending on what information you have: If base, b, and vertical height, h, then 0.5*b*h If two sides: a and b and included angle C, then 0.5*a*b*sin(C) If three sides: a, b and c then sqrt[s*(s-a)*(s-b)*(s-c)] where s = 0.5*(a+b+c) there are many other formulae.
How do you write algorithm for area of a triangle?
There are different formulae depending on what is known about the triangle:Base and height,Three sides,Two sides and included angle,Two angles and side,Coordinates of vertices,Plus other variations.A single algorithm to cover all these will be too complicated.
Can a scalene triangle be a triangle?
Yes, a scalene triangle can be a triangle.
What is a nested triangle?
a triangle in a triangle
How do you calculate the length of a right angled triangle using the sine formulae?
The answer depends on what other information you have about the triangle.
Who invent formula to find the area of triangle?
There are several different formulae for the area of a triangle - depending on the available information - and these were invented by different people.
How do you calculate angles in a scalene triangle?
If you know the lengths of the sides, you can use the cosine rule. If you have information about other aspects of the triangle, then other formulae will apply.
Formulae of trigonometry?
For a right angle triangle the formulae are:- Sine = opposite/hypotenuse Cosine = adjacent/hypotenuse Tangent = opposite/adjacent An easy way to remember them is: SOH-CAH-TOA
How do you calculate area of a triangle without knowing the height?
There are different formulae, depending on what you DO know. Here you will find several: http://en.wikipedia.org/wiki/Triangle#Computing_the_area_of_a_triangle
How do you use formula of a triangle?
There are many formulae for triangles: Some formulae will calculate sides given angles or conversely. Some will calculate the area. It is not possible to say how you would use a formula without knowing what it is for!
What is the formala for a triangle?
There is not one, but several formulae for triangles - depending on whether you want to calculate the angles, the lengths of the sides, the perimeter, the area, etc., and depending on what information is already known.
What is the formulae for the volume of a triangle based pyramid?
Volume of a pyramid = 1/3*base area*height in cubic units
What is the formula area of an triangle?
It depends on what information you have.There are different formulae for when you know:base and vertical heightone side and two anglestwo sides and an anglethree sidesMost of these are reasonably straightforward to compute. There are more complex formulae to cater for other scenarios.
Different formulae for finding out the area of the triangle?
i know only one i hope this helps 1/2 base x height
What is the derivation of the formulae of the surface area of a cone?
You can approximate the surface area by lots of triangles (base of the triangle on the base of the cone, and tip of the triangle at the tip of the cone), and analyze what happens when the triangles get narrower and narrower.
Who invent the formula to find the area of rectangle?
There are several different formulae for the area of a triangle - depending on the available information - and these were invented by different people.
