Question 1

What is the formula for determining the area of a triangle on a coordinate plane?

  • A = 1/3 | x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2) |
  • A = 1/2 | x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2) |
  • A = x1 + x2 + x3

πŸ’‘ Hint: Remember to account for the half and absolute value.

Question 2

Is the area of a triangle always a positive value?

  • True
  • False

πŸ’‘ Hint: Think about what area represents geometrically.
