Which statement provides a valid justification for why all circles are similar?

All circles have the same shape - a circle - so they must be similar.

All circles have no angles and no sides, so they must be similar.

I can translate any circle exactly onto another, so they must be similar.

I can translate the center of any circle to the center of another, and dilate from that center by an appropriate scale factor, so they must be similar.

Determine if the triangles are similar. If so, state the similarity transformations.
Similarity transformation - What transformations (translation, reflection, rotation) would you use to move one similar shape onto the other. A similarity transformation ends with a dilation by a scale factor to resize one shape to the other.

Shadow Problem

There is a pine tree that may be too close to Jamal’s house. He can’t physically measure the tree, but he thinks it may hit his house someday. He is 6 feet tall and has a shadow that is 4 feet. At the same time of day, the tree casts a shadow that is 28 feet.

Use the GeoGebra tool to set an example.

Draw and label a picture to represent this scenario. Using the measurements, determine the height of the tree.

If the base of the tree is 80 feet from the house, will it hit the house if it falls? Justify your answer.

Another Shadow Problem

Cathy is thinking of getting a tree planted in her yard to block the view of the new streetlight that her neighborhood is having installed. She is 5’ 6” tall and she makes an 8’ shadow with the ground. At the same time of day, the new streetlight makes a 24’ shadow with the ground.
