1. 6. 2. 3. 4. 5. The quadrilateral family tree: 1. A quadrilateral is a closed figure with four sides and four angles.
2. A parallelogram is a quadrilateral with two pairs of parallel sides. 3. A rectangle is a quadrilateral with four right angles.
4. A rhombus is a quadrilateral with 4 congruent sides. 5. A square is a quadrilateral with 4 right angles and 4 congruent sides.
1 + 2 + 3 + 4 = 360° 1 2 6. A trapezoid is a quadrilateral with 1 pair of parallel sides. 4 3 The sum of the angles in any quadrilateral is always 360°.

Review – Short Write • Compare and contrast triangles and quadrilaterals. Angle sum for a triangle is 180 while it is 360 for a quadrilateral.
Student Self Assessment • Raise hand 1-5 based on how well you understand the material. • Did not understand at all • Did not get it but could with a little more help • Sort of get, need more practice • Understand, need more practice • Fully understand and ready for quiz
