phi2 and phi3 related CP Volation Measurements

We present the recent results from BaBar and Belle experiments on the measurements of the angles, $\phi_2(\alpha)$ and $\phi_3(\gamma)$, in the CKM unitarity triangle. The results include measurements of $CP$ violation in charmless $B$ decays such as $B^0 \to \pi^+\pi^-$, and determination of $\phi_3(\gamma)$ based on $B \to DK$ Dalitz plot analysis.
