A Hard Geometry Problem on circle - Stack Exchange
A Hard Geometry Problem on circle. Ask Question Asked 2 years, 4 months ago. Active 1 year, MathJax is meant for complicated formulae that would be ambiguous or difficult to read as plain text. Hard Euclidean Geometry question. 0.Without loss of generality, we can consider $R=OC=OB=1$. From $\Delta OBC: \frac{OB}{\sin20}=\frac{BC}{\sin140}\Rightarrow BC=\frac{\sin140}{\sin20..Best answer · 3Join OA and AC angle AOC = 2xangle ABC=60 deg (center angle and circumference angle) OC=OA (radii) Triangle OAC is equilateral AC=OA=OC angle CAB =..3Hint. a bit of angle-chasing you should be able to establish$\angle ADC=70$. You can then use the sine rule in triangles$ODB$and$ODC$(as..0$$/angle(ABC)=30°// /angle(AOC)=2*angle(ABC)=60°//$$ So AOC is equilateral triangle (AO=AC=CO=R) $$/angle(CAB)=/angle(COB)/2=70° //angle(ACD)=70°$$..0Produce CD and meet the circle at E Join OA and AC angle APC = 60 deg (centre and circumference angles) OA = AC = OC Join BE angle CAB = angle CEB..0BCD is equal to 40 (OCD plus BCO). So the unknown corner of the triangle is 180 - (40 + 30) which is 110. ADC, CDB and ODB are supplementary, so AD..First join$AC$and$AO$. Now,$\angle ABC$is$30^\circ\$,so AOC is 60*=OC,OAC=OCA=(180*-60*)÷2=60*. Triangle AOC is equilateral Triangle,..[PDF]

What Are Euclidean and Non-Euclidean Geometry?
Balloons, Triangles, and AnglesWhat Is Euclidean Geometry?What Is Non-Euclidean Geometry?Non-Euclidean Geometry in The Real WorldWrap UpA few months ago, my daughter got her first balloon at her first birthday party. Ever since that day, balloons have become just about the most amazing thing in her world. After her party, she decided to call her balloon “ba,” and now pretty much everything that’s round has also been dubbed “ba.” A ball? A “ba.” The Moon? Yep, also a “ba.\"Why did she decide that balloons—and every other round object—are so fascinating? I might be biased in this belief, but I’ve come to the conclusion that it’s..See more on quickanddirtytips
