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

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

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

Both pairs of opposite sides are parallel
1. Give the most specific name for the quadrilateral. Explain. Parallelogram, Both pairs of opposite sides are parallel

Consecutive sides are congruent
1. Give the most specific name for the quadrilateral. Explain. Kite, Consecutive sides are congruent

Opposite sides are congruent
2. Tell whether enough information is given in the diagram to classify the quadrilateral by the indicated name. Explain. Yes, Opposite sides are congruent

Don’t know about the other sides
2. Tell whether enough information is given in the diagram to classify the quadrilateral by the indicated name. Explain. No, Don’t know about the other sides

Don’t know if one pair of opposite sides are parallel
