WebSep 15, 2024 · We need a different procedure for acute and obtuse triangles, since for an acute triangle the center of the circumscribed circle will be inside the triangle, and it will be outside for an obtuse triangle. Notice from the proof of Theorem 2.5 that the center \(O\) was on the perpendicular bisector of one of the sides (\(\overline{AB}\)). WebSep 4, 2024 · Theorem 7.3. 2. A line perpendicular to a radius at a point touching the circle must be a tangent. In Figure 7.3. 3, if O P ⊥ A B ↔ then A B ↔ must be a tangent; … sickle cell screening uk
