Hey guys.

I need lots of help.

I need to find out how to do these questions: Answers (showing your work, like how to get the answer) would be really great. I'm really stuck with this stuff. And its drving me insane because I don't undertsand it.

1. The vertices of a right triangle are A(3,3), B(-1,4), and C(1,-5). Find the area of the triangle.

2. For the line segment DE, one endpoint is D(3,1) and the midpoint is M(0,-4). Find the coordinates of endpoint E.

3.Triangle DEF is a right triangle with vertices D(-2,5), E(-4,1), and (2,3). Verify that the midpoint of the hypotenuse is equidistant from the three vertices of the triangle.

4. Verify that the vertices A(-6,1), B(2,-5), C(6,1), and D(2,4)are the vertices of a trapezoid.

5. Quadrilaterial RSTU has vertices R(3,2), S(0,4), T(-2,1), and U(1,-1). Verify that

a) quadrilateral RSTU is a square

b) the diagonals of quadrilateral RSTU perpendicularly bisect each other and are equal in length.

I know these are alot of questions....but if you guys could try and anser them all i'd really appercaite it.
