Encode the message Math is good. Break the message into groups of two letters and use the matrix M = How can the message be encoded? OA Translate each group into a sequence of integer pairs and add each to the identity matrix 0. Translate each group into a sequence of integer pairs and multiply each by M OC. Translate each group into a sequence of integer pairs and subtract each from the identity matrix D. Translate each group into a sequence of integer pairs and multiply each by M Encode the message. Give your answers as column matrices, where each matrix contains a pair of encoded letters. Give the matrices in the order they were encoded, which should correspond to the order of the original message 119 888888 (Type an integer or simplified fraction for each matrix element.) 29 15

et △ABC be a triangle in S^2 (the two-dimensional sphere). Let the dual point C'∈S^2 of C be defined by the following three conditions:(i) d(C' , A)=π/2(ii) d(C' , B)=π/2(iii) d(C' , C)≤π/2A' and B' are defined analogously. Thus we get a dual triangle △A' B' C'. More precisely, △ABC is a non-degenerate triangle, andit follows (you may assume) that △A' B' C' is too.(question) Are there triangles △ABC in S^2 identical to their own dual △A'B'C'? I would be very thankful if you could provide some explanation with the steps, thank you in advance.
