Angle

Standard 2.G.2 Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.

Right Angle

Cube Face Edge

Standard 2.G.3 Partition circles and rectangles into two, three, or four equal shares; describe the shares using the words halves, thirds, half of, a third of , etc.; and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
