Can someone walk me through these and help me get the right answer .... A quadrilateral has vertices (2, 0), (0, –2), (–2, 4), and (–4, 2). Which special quadrilateral is
formed by connecting the midpoints of the sides?
kite
rectangle
trapezoid
rhombus
2. Which of the following describes TVS? The vertices are T(1, 1), V(4, 0), and S(3, 5)
isosceles
scalene
right
equilateral
4. Verify that parallelogram ABCD with vertices A(–5, –1), B(–9, 6), C(–1, 5), and D(3, –2) is a
rhombus by showing that it is a parallelogram with perpendicular diagonal

Best ResponseYou've already chosen the best response.0hmmm so would it be a trapaoid? or a rhombus?

Best ResponseYou've already chosen the best response.1The second prob.... You have to figure the lengths of each side of the triangle... Equilaterla = all 3 sides the same isosceles = 2 sides the same scalene = all sides different right = 90 degree angle

Best ResponseYou've already chosen the best response.1yes, that is the length of that one side. THen you need to compare that to the length of the other sides..

Best ResponseYou've already chosen the best response.1Recall, if it is a right triangle, the 3 sides will satisfy the pythagorean theorem a^2 + b^2 = c^2 Here it does not, 20 + 10 = 26, NO Not a right triangle

Best ResponseYou've already chosen the best response.1If not a right triangle, you have to use the law of sines and law of cosines to figure side lengths.
