I apologize that it's so long, I just don't understand. I tried on as many as I could, but my teacher just doesn't care to help me understand it.
What I had trouble with:
1. ABCD is a rhombus with diagonals intersecting at E. If measure ABC is three times measure BAD, find measure EBC.
2.TUVW is a square with U(10,2) V(8,8) and W(2,6). Find the coordinates of T.
TRUE OR FALSE:
-a rectangle is always a parallelogram.
-the diagonals of a rhombus are always perpendicular.
-the diagonals of a square always bisect each other.
-a trapezoid always has two congruent sides
-the median of a trapezoid is always parallel to the bases
-a kite has exactly two congruent angles.
-if the diagonals of a parallelogram are perpendicular, the the parallelogram is a rectangle
3. In parallelogram ABCD, AB = 2x-7, BC = x+3y, CD = x+y and AD = 2x-y-1. Find the values of x and y.
