How you will know that the rock is metamorphic rock?
You can identify metamorphic rocks by various minerals or a lack of thereof (mineralogy), also by foliation: whether they're foliated or non-foliated. If they show presence of shistosity or gneissosity (alignment of minerals ) , fissility and grunular appearance.
What are the two categories of metamorphic rocks?
Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).
What do Metamorphic and Sedimentary rocks have in common?
It is more likely that igneous and metamorphic, or igneous and sedimentary rocks would have something in common than sedimentary and metamorphic. The reason is because the processes involved in making metamorphic rocks is completely different than the processes needed to make sedimentary rocks. Only high temperature, high pressure minerals such as olivine, pyroxene, amphibole can withstand these kinds of conditions. Take quartz and feldspar, two of the most abundant minerals found in sedimentary rocks, these minerals would not be found in abundance in metamorphic rocks because they are not high temperature, high pressure rocks. But the most simple answer is that all the major groups of rocks are made of minerals. Metamorphic has high pressure and Igneous does to and both made from a particle called magma.

Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
