I had this same question on a test and I guessed and got it right!
phi
  • phi
It may not be obvious but both angle C and angle BDR have the *same intercepted arc*
anonymous
  • anonymous
Oh
anonymous
  • anonymous
Thanks guys!
anonymous
  • anonymous
Appreciate it!

np
phi

If inscribed angles have the same arc, then they are both 1/2 of that arc. they both are equal to the same value.
anonymous
  • anonymous
Yeah
phi
  • phi
so if C=63 what is angle BDR ?
anonymous
  • anonymous
But 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.
phi
  • phi
Yes, 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)
phi
  • phi
so if C=63 what is angle BDR ?
anonymous
  • anonymous
90?
anonymous
  • anonymous
Oh it should actually be 63 right?And not 90?
phi
  • phi
I 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|
phi
  • phi
and (a bit mysterious but true) |dw:1435584627499:dw|
phi
  • phi
so if both angle C and angle BDR = 1/2 arc BD, then angle C must equal angle BDR
anonymous
  • anonymous
Huh. Wow. Well I guess I'm awake now
anonymous
  • anonymous
So it is 63
phi
  • phi
yes
anonymous
  • anonymous
Wow

Mind Blown Lol

It 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.

Yea 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
anonymous
  • anonymous
What 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.
phi
  • phi
Yes, geometry can be painful to learn. But it's worth tackling just to get used to thinking hard.
anonymous
  • anonymous
Yeah, I agree. I used to think the same way about Punnet Squares, but now I'm almost like a pro! Lol

Would you mind helping me with a few more?

I'll give you medals and fan you too

please make a new post.
