Look at the shapes shown. What are the names of the orange, green, and purple shapes? For the purple shapes, tell 1 word that could name any of these shapes.
Orange: hexagon; Green: triangle; Purple: parallelograms (quadrilateral and quadrangle are also acceptable).
Where do you see lines, line segments, or rays in these figures?
The sides of the figures are line segments.
Where do you see right angles?
In the rectangle and the square.
Where do you see obtuse and acute angles?
Obtuse angles in the hexagon and the parallelogram; acute angles in the triangle and parallelogram.
Sketch a way to partition the triangle into equal halves.
Students should draw a vertical line down the middle.
Sketch a way to partition the hexagon into sixths.
Possible solution: Students divide the hexagon in half from vertex to vertex and then divide each half into thirds.
