ikr
OpenStudy (danieldjpon3):
just compare the radius of the circles by choosing two places from each and if they are equal then they are similar
OpenStudy (danieldjpon3):
in the small circle, i choose the green line as the radius and that is equal to the small red line below.. Let's look at the big circle now: the radius is 5 units from the point (4,4) to (8,4) and when we apply Pythgorean's theorem, we find other radius to be 5 again
OpenStudy (danieldjpon3):
so 2/5 =2/5 : they are similar
OpenStudy (danieldjpon3):
they should have 2/5 ratio: if you draw a line in a small circle for example, 5/2 times of its length should be equal to that of the big one, the easiest way to do it is to choose the radius because you can draw it using the center and find the length easily

ima go this kid fell in the water by my enclosure
OpenStudy (wolf1728):
Circle "B" has a radius of 2 (it goes from -1 to -3)
Circle "A" has a radius of 5 (4 to -1 =5)
OpenStudy (wolf1728):
I'd say the proportionality for B to A is simply
2 : 5

or am i crazy? like I just saw this black kid fall in my enclosure?
OpenStudy (wolf1728):
Is that what the question asks? (Are these 2 circles similar?)
