What is the area, in square units, of a triangle whose vertices are at (4,-1), (10,3) and (4,5) ?

How to do this?

  • Please help on geometry - analytic geometry - ,

    It helps if you plot the points first, then you can find the length of the sides of the triangle.
    area of a triangle is
    1/2 base times height.

    ok thanks

    I could also i think find the area of the square/rectangle and minus the pieces that are not part of the triangle

    Knights, If you are in analytic geometry, I am pretty certain your teacher expects an analytical approach, not a graphical approach. See the example I posted.
