  Angularity is a class of event-shape observables that can be measured in
deep-inelastic scattering. With its continuous parameter $a$ one can
interpolate angularity between thrust and broadening and further access beyond
the region. Providing such systematic way to access various observables makes
angularity attractive in analysis with event shapes. We give the definition of
angularity for DIS and factorize the cross-section by using soft-collinear
effective theory. The factorization is valid in a wide range of $a$ below and
above thrust region but invalid in broadening limit. It contains an angularity
beam function, which is new result and we give the expression at
$\mathcal{O}(\as)$. We also perform large log resummation of angularity and
make predictions at various values of $a$ at next-to-next-to-leading log
accuracy.
