Math - Shape and Space

I can describe and compare the sides and angles of regular and irregular polygons.

I can demonstrate an understanding of angles by classifying angles according to their measure and determine angle measures in degrees

I can draw and label angles 

LINES

• Horizontal - straight line from left to right

• Vertical - straight line from up to down

• Parallel - two or more lines evenly spaced out from one another; the two lines will never intersect

• Intersecting - two or more lines that go through each other   + x #

• Perpendicular - two lines that make an right angle _|_

SHAPES

Polygons                                                                                                                                             

• Regular polygon - all the sides are the same length

• Irregular polygon -  all the sides are not the same lengths []

ANGLES

BENCHMARKS: 

Right angle - 90   

straight angle - 180      

full turn - 360

TYPES OF ANGLES: 

• acute - less than 90 , obtuse - more than 90 but less than 180, 

reflex - more than 180

TYPES OF ANGLES:

            Acute - less than 90 degrees

            Obtuse - greater than 90 degrees but less than 180 degrees

            Reflex - greater than 180 degrees

In order to showcase our understanding of angles, lines, and polygons, we created beautiful artwork inspired by Wassily Kandinsky
