By Thales' theorem, any triangle inscribed in a semicircle with a vertex at each of the endpoints of the semicircle and the third vertex elsewhere on the semicircle is a right triangle, with right angle at the third vertex. All lines intersecting the semicircle perpendicularly are concurrent at the center of the circle containing the given Angle Inscribed in a Semicircle [11/07/2001] Prove that any angle inscribed in a semicircle is a right angle. Angle Measurements of Triangles inside Semicircle [11/26/1998] If the area of a triangle inside a semicircle is equal to the area outside the triangle within the semicircle, then find the values of the acute angles in the triangle.

May 17, 2017В В· Hi all, Please help me create an IF statement to solve the problem I have here. I am given an angle (for interest sake it is a wind direction), say 280 degrees. I then have another angle which might be say 060 degrees. What I need is a function that can designate "Black" or "Red" determined on what side of the semicircle an angle appears on. In the figure above, no matter how you move the points P,Q and R, the triangle PQR is always a right triangle, and the angle в€ PRQ is always a right angle. A practical application - finding the center of a circle. The converse of Thales Theorem is useful when you are trying to find the center of a circle.

Second circle theorem: There are 2 Geogebra windows here; newer one just below, & original lower down. For the first one, try moving the point P about. Where does P have to be for angle О± to be acute? and where must P be for angle О± to be obtuse? So where must P вЂ¦
