What tree is this?

Maple or pinoak?

Hard maple

Maple Leafs

Certainly a maple.

Red maple

Looks like a Japanese red maple.

Looks like a Norway or a sugar maple. Picture of the buds or seeds would give it away.

Norway maple leaves are bigger (with much larger stems) than sugar (hard) maple leaves, but are similar in shape.

The Norway maples have a milky sap on the stems of actively growing leaves. Pull a leaf off of a growing twig, and you'll see the milky sap of a Norway Maple.

Other non-maple trees have milky sap; but if you have a maple-like leaf with milky sap, it's very likely a Norway maple.

Yep, some kind of maple.

Norway maple .
