4. diagonals are congruent
1. Give the most specific name for the quadrilateral. Explain.
Rectangle,
diagonals are congruent

5. One pair of opposite sides parallel, base angles are congruent
1. Give the most specific name for the quadrilateral. Explain.
Isosceles Trapezoid,
One pair of opposite sides parallel, base angles are congruent

6. Rectangle – diagonals are congruent
1. Give the most specific name for the quadrilateral. Explain.
Square,
Rectangle – diagonals are congruent
Rhombus – diagonals are perpendicular
So, shape is a rectangle and rhombus
