2. Lucia and Claudine went to visit
their Lola Clara in the city. They rode
on a bus which rolled out into the
highway. They saw signs like these as
they were traveling.
5. What do we call a closed figure
with no sides? How about figures
with 3 sides? What about with four
sides?
• Plane figures are closed figures.
Plane figures with 3 sides are called
triangles. Those with four sides are
called quadrilaterals, those without
sides are called circles.
