Best ResponseYou've already chosen the best response.0I had this same question on a test and I guessed and got it right!

Best ResponseYou've already chosen the best response.1It may not be obvious but both angle C and angle BDR have the *same intercepted arc*

Best ResponseYou've already chosen the best response.1If inscribed angles have the same arc, then they are both 1/2 of that arc. they both are equal to the same value.

Best ResponseYou've already chosen the best response.1so if C=63 what is angle BDR ?

Best ResponseYou've already chosen the best response.0But sometimes it gets a little confusing because looks like it's not actually intercepting the arch and is just running straight through. That's usually what stumps me.

Best ResponseYou've already chosen the best response.1Yes, the tangent is a special case. But we (or somebody) can prove the angle BDR equals 1/2 of the arc from B to D the short way (through A)

Best ResponseYou've already chosen the best response.0Oh it should actually be 63 right?And not 90?

Best ResponseYou've already chosen the best response.1I guess you are missing the point. Do you agree that angle C is 1/2 of its intercepted arc (which is from B to D the short way) dw:1435584558053:dw

Best ResponseYou've already chosen the best response.1and (a bit mysterious but true) dw:1435584627499:dw

Best ResponseYou've already chosen the best response.1so if both angle C and angle BDR = 1/2 arc BD, then angle C must equal angle BDR

Best ResponseYou've already chosen the best response.1It is the only reason we bother to learn this stuff... to see how it is possible to take "simple facts" and deduce stuff that is totally not obvious. The more you do of this, the better you are able to "think" (make logical deductions). but it takes practice to get your brain to do it.

Best ResponseYou've already chosen the best response.0Yea I know. I found Algebra a heck of a lot easier than Geometry. Many other people argue saying that Geometry is "Easy As Pie", but I disagree

Best ResponseYou've already chosen the best response.0What I trying to do is get help with all of these questions that I missed on this test so I can find out where in the world I went wrong with them. I'm not just here for answers. I Need "Explanations" too.

Best ResponseYou've already chosen the best response.1Yes, geometry can be painful to learn. But it's worth tackling just to get used to thinking hard.

Best ResponseYou've already chosen the best response.0Yeah, I agree. I used to think the same way about Punnet Squares, but now I'm almost like a pro! Lol
