What statement could you use to conclude that JKLM is a parallelogram?

A.) LK || MJ and JK ≅ LM

B.) MN ≅ KN and LN ≅ LK

C.) MJ ≅ JK AND LM ≅ LK

D.) LK || MJ and LK ≅ MJ

How can you tell when x and y are not directly proportional?

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

Given abc find the values of x and y. in your final answer, include all of your calculations.
