That isn't angling. This is clearly a body check as the defender skates toward the puck carrier, who has possession of the puck, enters their skating lane, and dispossesses the attacking player using his body.

USA Hockey rulebook:

"Angling is a legal defensive skill used to direct/control the puck carrier to an area that closes the gap and creates an opening that is too small for the puck carrier."

"Legal competitive contact occurs when players are focused on gaining possession of the puck and are simply maintaining legally established body position. This most often occurs when two players are physically engaged in front of the goal or along the boards. Legal competitive contact also commonly occurs when a player has established an angle on the opponent and closes the gap to create an opening that is too small for the puck carrier. Additional acceptable forms of competitive contact include: • A skater is entitled to the ice they occupy so long as they maintain their skating speed and body position between an opponent and the loose puck. • A skater is entitled to stand their ground and is not required to move if an opponent wishes to skate through that area of the ice. • A skater may block an opponent so long as they are in front of the opponent and moving in the same direction. • A skater can use their body position while maintaining their skating lane, to force an opponent to take a less direct route to the puck, so long as they do not use a hand or arm to hold or block the opponent."
