Just two multiple choice.

1. the coordinates of triangle xyz are x(-5, 5), y(-3, 2), and z(4, 0).
which statement correctly describes whether triangle xyz is a right triangle?
a. triangle xyz is a right triangle because xy is perpendicular to xz.
b. triangle xyz is a right triangle because xy is perpendicular to yz.
c. triangle xyz is a right triangle because xz is perpendicular to yz.
d. triangle xyz is not a right triangle because no two sides are perpendicular.

2. the coordinates of the vertices of a quadrilateral defg are d(-2, 5), e(2, 4), f(0, 0), and g(-4, 1).
which statement correctly describes whether quadrilateral defg is a rhombus?
a. quadrilateral defg is not a rhombus because opposite sides are parallel but the four sides do not all have the same length.
b. quadrilateral defg is not a rhombus because there is only one pair of opposite sides that are parallel.
c. quadrilateral defg is not a rhombus because there are no pairs of parallel sides.
d. quadrilateral defg is a rhombus because opposite sides are parallel and all four sides have the same length.
