Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.

No, a limestone is a sedimentary rock. There are three types of rocks: sedimentary, metamorphic and igneous. That's the simple answer for the complex distinctions between the types of rocks.
Igneous rocks are formed from the cooling of magma that rises up from the mantle. Sedimentary rocks are formed from the compaction of small grains of weathered igneaous or metamorphic rock. Metamorphic rocks are formed from the action of heat and/or pressure on igneous or sedimentary rocks. Finally, subduction process at certain plate boundaries return all three rock types to the mantle. So there exists a contiuous cycle between the three types of rock; starting with igneous rocks, perhaps becoming sedimentary rock or metamorphic rock or both, then returning to the mantle.
They are both rocks. Sedimentary can contain metamorphic rocks. and vice versa.
igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
basalt is an igneous rock. Igneous is one of the three main types of rock, (igneous, metamorphic and sedimentary) and means, "formed from fire" It includes any rock that cooled directly from a magma or lava state.
A laccolith is an igneous formation between two sedimentary layers
