Area is 6.0000 square units.

  • The perimeter is 11.2111 units.
  • All three angles are less than 90 degrees, so this is an acute triangle.
  • The centroid (geometric center) is at (2.000, 1.000). The three medians all meet here.

Next stepTo scale the triangle, multiply each coordinate by the same factor - the area scales by the square of that factor.
