Polygons with four sides

2. Today’s Objective We will I will
classify two-dimensional figures using a graphic organizer based on their attributes and properties.
predict the classification of a two-dimensional figure and write justification for my prediction based on its characteristics.

7. Types of Quadrilaterals
Square: Quadrilateral with four equal sides and four right angles (90 degrees)
Indicates equal sides
Box indicates 900 angle

8. Types of Quadrilaterals
Rectangle: Quadrilateral with two pairs of equal sides and four right angles (90 degrees)
Indicates equal sides
Box indicates 900 angle

9. Types of Quadrilaterals
Parallelogram: Quadrilateral with opposite sides that are parallel and of equal length and opposite angles are equal
Indicates equal sides

10. Types of Quadrilaterals
Rhombus: Parallelogram with four equal sides and opposite angles equal
Indicates equal sides

11. Types of Quadrilaterals
Trapezoid: Quadrilateral with one pair of parallel sides
Parallel sides never meet.

12. Types of Quadrilaterals
Irregular shapes: Quadrilateral with no equal sides and no equal angles

18. Interior Angles
Interior angles: An interior angle (or internal angle) is an angle formed by two sides of a simple polygon that share an endpoint
Interior angles of a quadrilateral always equal 360 degrees

217
360 – 217 =
143
Angle x = 143
