Classify quadrilaterals

Learning Objectives Identify a shape as a quadrilateral based on its attributes. Define a quadrilateral as a closed shape with four straight sides and four angles. Name specific quadrilaterals: square, rectangle, rhombus, parallelogram, and trapezoid. Describe the attributes of specific quadrilaterals, such as the number of equal sides, right angles, and pairs of parallel sides. Compare and contrast two different types of quadrilaterals (e.g., a square and a rhombus). Draw examples of at least three different quadrilaterals. Look around the room! How many four-sided shapes can you spot? 🪟📖 We are going to learn the special names for all those four-sided shapes you see. These shapes are called quadrilaterals, and learning about them helps us describe and build things in ou...

TermDefinitionExample QuadrilateralAny flat, closed shape with exactly 4 straight sides and 4 corners (angles).A door, a window, or a kite are all quadrilaterals. Parallel LinesTwo lines that are always the same distance apart and will never, ever cross, like railroad tracks.The top and bottom edges of a book are parallel. Right AngleA special angle that makes a perfect square corner, like the corner of a piece of paper.A square has four right angles. SquareA quadrilateral with 4 equal sides AND 4 right angles.A cheese cracker is often a square. RectangleA quadrilateral with 4 right angles. Its opposite sides are equal in length.A dollar bill is a rectangle. RhombusA quadrilateral with 4 equal sides. Its angles don't have to be right angles.A diamond shape on a playing card is a rhom...

The Quadrilateral Check Sides = 4, Angles = 4 To know if a shape is a quadrilateral, it must have exactly four sides and four angles. The Square & Rectangle Check Number of Right Angles = 4 If a quadrilateral has four right angles (square corners), it is either a rectangle or a square. The Square & Rhombus Check Number of Equal Sides = 4 If a quadrilateral has four sides that are all the same length, it is either a square or a rhombus.
