Sorting and Classifying

Shape Properties• Parallelogram-Four-sided shape with two sets of parallel sides and

opposite sides congruent• Square-Four sided shape with all sides equal and opposite sides parallel• Rectangle-four-sided shape with opposite side’s equal lengths and

parallel• Rhombus- Four Sided shape with all sides equal length and opposite

sides are parallel; no right angles• Kite is a quadrilateral whose four sides can be grouped into two pairs of

equal-length sides that are beside (adjacent to) each other• Trapezoid- A quadrilateral with exactly one pair of parallel sides. • Equilateral Triangle-Three sided shape with 3 equal length sides and

equal angles inside• Isosceles Triangle- Three sided shape with two equal length sides • Right Angle Triangle- three sided shape with a right angle• Scalene Triangle-A three sided shape with all sides different lengths

Discussion Topics• According to the definition of a trapezoid, a

parallelogram cannot be a trapezoid. Explain why.• Explain why a rectangle is ALWAYS a parallelogram.• Explain why all squares are quadrilaterals.• Explain why a trapezoid may not be a

parallelogram.• Explain why all squares are rectangles, but not all

rectangles are squares.

Symmetry

• Symmetric figures are figures that can be folded to make two halves that are congruent (same) to each other

• The lines that divide a symmetric figure into congruent halves are called lines of symmetry

• This square has 4 lines of symmetry. If you fold the square, the two halves will lie on top of each other.

Triangles

Triangles can have 3, 1, or 0 lines of symmetry

Quadrilaterals

Trapezoid1 Line of Symmetry

TrapezoidNo Lines of Symmetry

ParallelogramNo Lines of Symmetry

• Regular Polygon- a shape with 2 or more EQUAL sides (square, pentagon, hexagon)

• The number of lines of symmetry of a regular polygon is always the same as the number of edges.

An Equilateral triangleWould have how many lines of symmetry?

A regular octagon would have how many lines of symmetry?

A regular hexagon would have how many lines of symmetry?

• Irregular Polygon- a shape with 2 or more sides that are not equal (rectangle, isosceles triangle)

A rectangle would have how many lines of symmetry?

An isosceles triangle would have how many lines of symmetry?

DID YOU KNOW???Polygons with an odd number of sides (triangle, pentagon) have lines of symmetry that goes from midpoint of a side through a vertex.
