Getty Images Answer Image A Correct Incorrect A Answer Image B Correct Incorrect B Image: Via BuzzFeed C Correct Incorrect Via BuzzFeed C Via BuzzFeed Correct! Wrong! A A ray starts at one point and continues in one direction infinitely. Via BuzzFeed Can you identify the set of parallel lines? Getty Images Answer Image A Correct Incorrect A Answer Image B Correct Incorrect B Answer Image C Correct Incorrect C Correct! Wrong! C Parallel lines do not intersect. Via BuzzFeed Which of these is a trapezoid? Getty Images Answer Image A Correct Incorrect A Answer Image B Correct Incorrect B Answer Image Correct Incorrect Image: Via Getty Images C Correct Incorrect Via Getty Images C Via Getty Images Correct! Wrong! C Trapezoids have one pair of opposite, parallel sides. Via Getty Images Which formula should you use to find the area of a circle? Getty Images Answer Image A Correct Incorrect A Answer Image B Correct Incorrect B Answer Image C Correct Incorrect C Answer Image D Correct Incorrect D Correct! Wrong! B The area of a circle can be found by multiplying pi by the square of the radius. Which of these lines depicts the radius of a circle? Getty Images Answer Image A Correct Incorrect A Answer Image B Correct Incorrect B Answer Image C Correct Incorrect C Correct! Wrong! A The radius starts at the center of a circle and ends at its perimeter. Via BuzzFeed BuzzFeed This shape is equilateral. Correct Incorrect This shape is equilateral. This shape is a hexagon. Correct Incorrect This shape is a hexagon. This shape is equiangular. Correct Incorrect This shape is equiangular. This shape has acute angles. Correct Incorrect This shape has acute angles. Correct! Wrong! This shape has acute angles. The shape has obtuse angles, because they are all greater than 90º. Which of these is an obtuse angle? Getty Images Answer Image A Correct Incorrect A Answer Image B Correct Incorrect B Answer Image C Correct Incorrect C Image: Via BuzzFeed D Correct Incorrect Via BuzzFeed D Via BuzzFeed Correct! Wrong! A An obtuse angle is any angle between 90° and 180º. What are supplementary angles? Getty Images Angles that add up to 90º. Correct Incorrect Angles that add up to 90º. Angles that add up to 180º. Correct Incorrect Angles that add up to 180º. Opposite angles that are equal in measure. Correct Incorrect Opposite angles that are equal in measure. Opposite angles that add up to 90º. Correct Incorrect Opposite angles that add up to 90º. Correct! Wrong! Supplementary angles add up to 180º. BuzzFeed 90º Correct Incorrect 90º 70º Correct Incorrect 70º 160º Correct Incorrect 160º It's impossible to solve for this. Correct Incorrect It's impossible to solve for this. Correct! Wrong! 70º These two angles are complementary, meaning their sum equals 90º. 90 minus 20 is 70, so angle X = 70º. BuzzFeed 35º Correct Incorrect 35º 55º Correct Incorrect 55º 125º Correct Incorrect 125º 235º Correct Incorrect 235º Correct! Wrong! 55º These two angles are supplementary angles, meaning they add up to 180º. 180 minus 125 is 55, so Z = 55º. Via BuzzFeed BuzzFeed A Correct Incorrect A B Correct Incorrect B C Correct Incorrect C D Correct Incorrect D Correct! Wrong! C The hypotenuse is the longest side of a right triangle. Via BuzzFeed And finally, is the following statement true or false?All squares are rectangles, but not all rectangles are squares. Getty Images True Correct Incorrect True False Correct Incorrect False Correct! Wrong! True A rectangle has four right angles and the opposite sides are equal — all of which is true for squares. But every side of a square must be equilateral, which is not true of rectangles.
