How Well Do You Remember These Basic Math Terms?

Whoever put this quiz up here needs to go back to school. There are at least 3 wrong answers.

5/9 Q3 didn’t show letters in the diagram. Were we calculating sides or angles?

What's the point of continuing after Q3, with a wrong answer. Compounded by two possible correct answers being given.

#3 is dead wrong! Pythagorean theorem involves the squaring if the sides.

No comments. You guys know better than I am!

Thank you for the answers! I think #7 could be quadratic formula or equation!

question 3 is incorrect ! Pythagoras would not be happy :(

Actually, I'm a mathematical genius, so I take the statement "You should have studied more" as quite an insult. It seems as if the test maker was consuming psychedelic mushrooms when they were constructing the quiz because, as others have also commented, several answers were wrong.

There are several wrong answers here. The actual axes were not defined for the sine wave, and the triangle cannot be evaluated without some indication of relative side length. The wrong Pythagorean Theorem is covered below. The Quizmaster gets an "F".

Pythagoras got lost somewhere !!!

Wrong answers accepted.

Whoever put up this quiz does not know the Pythagorean Theorem. A + B = C ???!!!

frank romano od, I agree

The correct answer question is the third answer, not the second answer.

the correct answer for hypotenuse is C squared is equal to a squared plus b squared.
