Objectives
-learn polygons
-use the reflectioinal symmetry and rotational symmetry.
-learn regular polygon, center of a regular polygon, center angle of a regular polygon, and axis of symmetry.

Vocublary: polygon- a figure formed by three or more segments and at each endpoint each segment intersects exactly at two other segments and no two segments are colliner. sides of the polygon- the segments of a polygon. vertices of the polygon- the common endpoints of a polygon. equiangular polygon-all angles are congruent. equilateral polygon- all sides are congruent. regular polygon- all angles are congruent and all sides are congruent. reflectional symmetry- reflection across the line is exactly the same. axis of semmetry- the line that is reflectied across. triangles classified by number of congruent sides-
three congruent sides: equilateral
no congruent sides: scalene
at least two congruent sides: isosceles Rotational symmetry- has to have at least one rotation, that is not 0 degrees or multiples of 360 degrees that coincides with the original image.

properties of quadrilaterals

objectives
-Learn the definition of quadrilateral parallelogram, rombus,rectangle, square, and trapezoide.
-Figure out the properties of quadrilaterals and the relationships between the properties.

Vocabulary: Quadrilateral- a four sides polygon. trapezoide- a quadrilateral that has one pair of parallel sides. parallelogram- a quadrilateral that has two pair of parallel sides. Rohmbus- a quadrilateral that has four congruent sides. Rectangle- a quadrilateral that has four right andles Square- a quadrilateral that has four righr angles and that has four congruent sides.

Symmetry in polygons- the dogs face is symmetrical
