Question

Part B Create a line through point D. perpendicular to AB. Mark the intersection of AB and the perpendicular line, and label it point E. What does DE represent? Explain your reasoning,​

Answer 1

Answer:

Since point D is the center of the circle that will be inscribed, and the inscribed circle will intersect AB at point E, AB  is tangent to the inscribed circle. Since DE is perpendicular to tangent AB , DE is the radius of the largest circle that will fit within triangle ABC .
