Understanding Polygons and Angles

How many angles does this polygon have? How many right angles? Name the figure.

• 3 angles, 1 right angle, Triangle

• 4 angles, 2 right angles, Rectangle

• 5 angles, 0 right angles, Pentagon

• 6 angles, 0 right angles, Hexagon

Which of the following options correctly describes the task: Draw 2 polygons and then draw 2 figures that are NOT polygons?

• Draw 2 triangles and 2 circles

• Draw 2 squares and 2 lines

• Draw 2 rectangles and 2 ellipses

• Draw 2 hexagons and 2 stars

How are these polygons alike?

• They all have equal sides.

• They all have equal angles.

• They are all quadrilaterals.

• They are all triangles.

Name the polygon.

• Pentagon

• Hexagon

• Square

• Triangle
