Question

Given vertices A(0,0), B(5,0),C(0,5), determine whether triangle ABC is a right triangle. a. yes c. insufficient information b. no

Answer 1

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.
