PLEASE HELP

Answer 1

@ganeshie8 help please

Answer 2

There are many options;
trapezoid - bases are parallel
parallelogram - opposites are parallel
square - all sides are equal, opposites parallel, diagonals are perpendicular
rectangle - four right angles, opposites congruent
rhombus - opposites are parallel, diagonals are perpendicular
kite - one pair of oppositie angles are congruent and diagonals perpendicular, two pairs of congruent sides.

Put the coordinates on a graph and look at the above descriptions >.<

Answer 3

would it be parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular? @Jadeishere

Answer 4

Yes, it would be a parallelogram :D YAY! Good job and Welcome to Openstudy!

Answer 9

How can you prove a triangle is a right triangle?

i think its between either B. Use the slope formula to see if any sides are perpendicular.
or D. Use the slope formula to see if any sides are parallel @Jadeishere

Answer 10

You'd want to use the slope formula to see if any are perpendicular because a perpendicular angle is a right angle, which would create a right triangle - and triangles CANNOT have any parallel sides :)
