Help pleaseeee. 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.
