We’re given a right triangle with an incircle inside.
Two tangent segments are known:
• CD = 12
• EB = 18
From just those two numbers, we can determine:
• The full hypotenuse
• The radius of the incircle
• And the exact area of the purple region
In this video we:
• Use equal tangent segment properties
• Apply the Pythagorean theorem
• Solve a quadratic equation
• And compute the final area cleanly
Pause the video and try solving it before watching the full solution.
💬 Comment: When did you realize the hypotenuse was 30?
