Question

Consider the following similar figures. Which of the following is not true?

  1. straight angle straight J equals straight angle straight T comma straight angle U equals straight angle straight K    
  2. JK corresponds to TU    
  3. VU corresponds to LK    
  4. fraction numerator T U over denominator J K end fraction equals fraction numerator T V over denominator L K end fraction    

hintHint:

If two triangles are similar, then the ratio of corresponding sides is equal to the ratio of the angle bisectors, altitudes, and medians of the two triangles.

The correct answer is: fraction numerator T U over denominator J K end fraction equals fraction numerator T V over denominator L K end fraction


    Consider the figure which is similar.
    By AA similarity, ΔTUV ~ ΔJKL
    fraction numerator T U over denominator J K end fraction equals fraction numerator T V over denominator J L end fraction ( ratio of corresponding sides are equal)
    So, option D is not correct.
