This paper deals with continuous families of linear embeddings (called linear isotopies) of finite complexes in the Euclidean plane $ E^2 $. Suppose $ f $ and $ g $ are two linear embeddings of a finite complex $ P $ with triangulation $ T $ into a simply connected open subset $ U $ of $ E^2 $ so that there is an orientation preserving homeomorphism $ H $ of $ E^2 $ to itself with $ H\circ f = g $. It is shown that there is a continuous family of embeddings $ h_t:P\to U $ ($ t\in [0,1] $) so that $ h_0=f $, $ h_1=g $, and for each $ t $, $ h_t $ is linear with respect to $ T $.

It is also shown that if $ P $ is a PL star-like disk in $ E^2 $ with a triangulation $ T $ which has no spanning edges and $ f $ is a homeomorphism of $ P $ which is the identity on $ \operatorname{Bd} P $ and is linear with respect to $ T $, then there is an continuous family of homeomorphisms $ h_t:P\to P $ ($ t\in [0,1] $) such that $ h_0=\mathrm{id} $, $ h_1=f $, and for each $ t $, $ h_t $ is linear with respect to $ T $. An example shows the necessity of the “star-like” requirement. A consequence of this last theorem is a linear isotopy version of the Alexander isotopy theorem — namely, if $ f $ and $ g $ are two PL embeddings of a disk $ P $ into $ E^2 $ so that $ f|_{\operatorname{Bd} P} = g|_{\operatorname{Bd} P} $, then there is a linear isotopy with respect to some triangulation of $ P $ which starts at $ f $, ends at $ g $, and leaves the boundary fixed throughout.
