Lines of Symmetry
Today's challenge was to fold and draw the lines of symmetry for the following shapes: square, rectangle, circle, rhombus, and trapezoid.

Here Zach folds a square to discover the 4 lines of symmetry. |
If you look closely you can see the 4 lines that Ben drew to indicate the lines of symmetry. |
Here Cara and Jordan show their circles that have many lines of symmetry. |

Michael responded to the question of how many lines of symmetry a circle has:"A circle has as many lines of symmetry as it does diameters." |
The next challenge was: "Find an equilateral triangle inside one of the shapes."
Ben explains how he met the challenge in the first cells. Steven's explanation is in the last two cells.
|
I was trying to find out how to get a equilateral triangle inside of a trapezoid.
|
I took the trapezoid and cut the corner of the trapezoid off and that made the equilateral triangle. I checked it by measuring it with a ruler in centimeters. |
|
|
First I took the trapezoid and started to make a equilateral triangle. I then checked it by measuring (two centimeters). |
