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
