the answser is given below

Explanation:

1)Both pairs of opposite sides are congruent--------parallelogram, rectangle, rhombus, square.

2.) Both pairs of opposite sides are parallel----parallelogram, rectangle, rhombus, square.

A)The midpoint M=( )

3  Diagonals are congruent.---- rectangle, square

4.) Diagonals bisect each other.parallelogram, rectangle, rhombus, square

b.) Slope FormulA ---------- m=

5.) Diagonals are perpendicular.---------rhombus, square, kite

--6.) Sides of polygon create a right angle.  right angle triangle, rectangle

c.) Distance Formula-------Distance between two points P(x1,y1) and Q(x2,y2) is given by: d(P, Q) = √ (x2 − x1)2 + (y2 − y1)2 _

7.) A triangle is isosceles/equilateral. and right angled triangle
