Francesca and Will want to find out if the triangle formed by connecting the points G, H, and I is a right triangle.
Francesca's Plan:
• Use the distance formula to find the lengths of the sides.
• Then see if the side lengths satisfy the equation a2+b2=c2 to see if it is a right triangle.
Will's plan:
• Find the slopes of the three sides.
• See if any two slopes are the same.
