Answer:
Yes, this triangle is a right triangle.
Step-by-step explanation:
Side AB lies on the x-axis and is thus horizontal. Side AC lies on the y-axis and is thus vertical. Sides AB and AC are therefore perpendicular to each other. This alone is enough info for us to conclude that this is a right triangle.
Side BC could be thought of as the hypotenuse.
