The table contains visual geometric problems where you must prove or find perpendicular relationships based on given properties. Below are the common solutions for the first few problems from this specific table. Problem 1: Prove Point lies outside plane ABCcap A cap B cap C Proof: By definition, if MBcap M cap B is perpendicular to any line in that plane, including ABcap A cap B If the drawing indicates (often given as a right angle in △ABCtriangle cap A cap B cap C ABcap A cap B is perpendicular to two intersecting lines ( MBcap M cap B ACcap A cap C ) in the plane AMCcap A cap M cap C Conclusion: By the criterion of perpendicularity, Problem 2: Prove Given: BMDCcap B cap M cap D cap C is a rectangle. Proof: BMDCcap B cap M cap D cap C In 10th-grade stereometry, typically refers to a specific
