Taking Pictures of Geometric Shapes - Justin Lang (Lesson by Annette Painter)

TRIANGLE: A three-sided polygon.
The sum of the angles of a
triangle is 180 degrees.
This is a picture of a speed-square
used for carpentry, it is a triangle-
shaped object.



RECTANGLE: A four-sided polygon
having all right angles. The sum of the
angles of a rectangle is 360 degrees.
This screen window shows a perfect
rectangle.

SQUARE: A four-sided polygon having equal-length
sides meeting at right angles.
The sum of the angles of a square is 360 degrees.
This is a picture of floor tile. This is to show
the square shape.

CIRCLE: A circle is the collection of
points in a plane that are all the
same distance from a fixed point.
This is a picture of a ceiling fan (duh).
I am focusing on the circle shape,
of which the light fixture has three.
They're concentric, in fact.


HEXAGON: A six-sided polygon.
The sum of the angles of a hexagon
is 720 degrees.
This is a picture of a socket
wrench attachment. I am
using it to show the hexagon
shape it has inside.
