Matlab corners detection for triangle and diamond.

Hi there, I would like you to detect the corners of a triangle and a diamond found in the attached files. I would also like you to rotate the image of '[login to view URL]' by 30 degrees in MATLAB without using 'imrotate' etc.. You are only allowed to use basic functions such as 'imread', 'imshow', 'imbinarize'. You will need to write MATLAB codes to solve the problem. Do not use MATLAB vision toolbox. You will need to submit a report of : -details of the algorithm (Theory/Concept) -explanation of MATLAB codes you wrote
