Zoom-In Exploring Geometry
Shapes, Symmetry, and Congruency in the World
Around Us by Lainie Ortiz
2
Understanding Goal Symmetry and geometry can be
seen in the world around us.
Investigative Question What might images of
buildings teach us about symmetry and geometry
in our world?
3
What kinds of shapes do you see? Do you see any
2-D shapes?
Can you name them?
4
What kinds of 3-D shapes do you see? Can you
describe them?
5

• Do you see any symmetry in this picture?
• Tell about it.
• What lines of
• symmetry do you
• see?

6
Do you think the other part of the building in
the picture will be symmetrical? Why or why
not?
7
Did you visualize this? Was the building
symmetrical? Why or why not? Did you see
other symmetrical areas in the picture?
8
What geometrical shapes do you see now? Can
you identify a shape and tell how many lines of
symmetry there are?
9
Do you see congruency in the picture? Tell about
it.
10
What kind of view is this? How does it affect
how you see geometry in the world? Would it
make a difference if the picture was flat?
11
Have you ever seen this view before? How do you
think this picture was taken? Where was this
picture taken? Describe views you have seen
similar to this. Think about the shapes you saw
and how the view affected what you saw.
