MHB Solve Proving 2 Triangles Cong. w/ Diam & Eq. Triangle (2-Col Proof)

AI Thread Summary
To solve the problem of proving two triangles congruent with a diameter and an equilateral triangle, it's essential to start by identifying the given elements. The discussion highlights that if two arcs are congruent, the angles subtending those arcs must also be equal. Additionally, if all three arcs are of equal length, it indicates that the triangle formed is equilateral. The presence of a bisector is suggested as a key component in establishing congruence. Understanding these relationships is crucial for completing the proof.

Not sure how to solve considering nothing is given as perpendicular or bisected.
Is anyone aware on how to solve this problem?

Well, to start with list what is given, then look at similar components
 
I think you will see that KH is a bisector and that will all angles equal and the sides equal

If all three arcs have the same length, then the triangle is equilateral.
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
