-
A.
Thales’ theorem
Thales’ theorem is a fundamental result in Euclidean geometry stating that any angle inscribed in a semicircle is a right angle.
-
B.
Brahmagupta–Fibonacci identity
The Brahmagupta–Fibonacci identity is a classical algebraic formula showing that the product of two sums of two squares can itself be expressed as a sum of two squares, fundamental in number theory and the study of quadratic forms.
-
C.
Conway circle theorem
The Conway circle theorem is a geometric result in triangle geometry that identifies a special circle associated with a triangle and certain constructed points, revealing notable collinearities and concyclicity relationships.
-
D.
Miquel point
The Miquel point is a notable point in triangle geometry defined as the common intersection of the circumcircles of three triangles formed by choosing one point on each side of a reference triangle.
-
E.
Pythagorean theorem
The Pythagorean theorem is a fundamental principle of geometry stating that in a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
