Interactive practice questions
Write down the ratio of the sides represented by $\sin\theta$sinθ.
The angle at vertex $B$B, $\angle ABC$∠ABC, is marked with a double blue arc, and is labeled as $\theta$θ. The vertical side $AC$AC is opposite $\angle ABC=\theta$∠ABC=θ and the horizontal side $BC$BC is adjacent $\angle ABC=\theta$∠ABC=θ. The angle at vertex $A$A, $\angle BAC$∠BAC, is marked with a single blue arc and is labeled as $\alpha$α.
