Question

ARE OF A TRIANGLE=?
(COORDINATE GEOMETRY?​

Answer 1

Answer:

• The formula of area of triangle formula in coordinate geometry the area of triangle in coordinate geometry is: A=12|x1(y2−y3)+x2(y3−y1)+x3(y1−y2)|

• Area of triangle with 3 points is: A=12|x1(y2−y3)+x2(y3−y1)+x3(y1−y2)|

• The formula of the area of triangle in coordinate geometry is: A=12|x1(y2−y3)+x2(y3−y1)+x3(y1−y2)|
