Proved
Step-by-step explanation:
Given
<u>Circle C</u>
--- radius
--- center
<u>Circle E</u>
--- center
Required
Prove their similarity
Translate circle C 8 units up;
The rule is:
So, we have:
Translate circle C' 7 units right;
The rule is:
So, we have:
<em>At this point, both circles now have the same center at (4,9)</em>
The next step is to dilate circle E by 4/3
This will only affect radius and not the center of E
The rule is:
So, we have:
-- equal radii
--- equal center

Transformations are without the equation already in them but I'll tell you what I know.
So your 5th problem is a reflection.
So the main thing is starting from the left of an equation you read the transformation from a point on the graph.
so for example, the first graph, reflects across the Y axis. What makes this the most is it's all linear. So transformations are like...
2x+2 this is really hard to teach as a linear.
okay picture something like this...
since the - is on the inside this means it reflects across the Y axis
since this is on the outside it reflects across the X axis.
try searching YTfor "understanding transformations" it's slightly confusing and I feel I'm too to teach it properly. It took me forever to understand the first I saw too so don't be discouraged.
