Given three points (A, B, C) that will always create a triangle with a positive area, calculate the location of the orthocenter and create a triangle that connects the orthocenter to the end points of the largest side in the triangle ABC. Display the internal angles of this new triangle and display whether it is isosceles, scalene, or equilateral, and whether it is acute, obtuse, or right. How to determine whether two floating-point values are equal? The comparison two floating-point values for an EXACT match is prone error, for this assignment if the absolute value of the difference between two floating-point values is less than 0.001 then the values will be considered equivalent.

Your task this week is to write a very simple spam classifier in python. it will classify messages as either spam (unwanted) or ham (wanted). the program will have a set of spam_words, words that are known to appear in spam messages. that set is included in the template file spam.pypreview the document. you will also define a spam threshold which reflects the allowed percentage of spam words in the message. you'll compute a 'spam indicator', which is the ratio of spam words to the total number of unique words in the message. if the spam indicator exceeds the spam threshold, the message is classified as spam. otherwise it is classified as ham. we'll assume that the spam threshold is a constant and has a value of 0.10. your program will prompt the user for a message and then will print the corresponding spam indicator with two decimal digits and the corresponding classification (spam or ham). the program will be case insensitive. the spam words are detected whether they are in lower case or upper case or mixed case. each word, spam or not, is counted once (even if it appears multiple times in the message.) the program will remove punctuation from the message before identifying the words and computing the spam indicator. for example '! ' must be identified as the spam word 'now'.
