2.09 Warm-up

How do dilations map angles? Make a conjecture.
[i]What do you think will happen if we dilate an angle?[/i]
A dilation from center D by a scale factor of 1/2 maps angle BAC to angle FGE.
Click on "Parallel lines #1". What is the relationship between angles BAC and HLI?
Click on "Parallel lines #2". What is the relationship between angles FGE and HLI?
Therefore, what can we say about angles BAC and FGE?
