5/8 3/4 1/2 9/16.

Answers

(5)/(8)=(5 * 2)/(8 * 2)=(10)/(16) \n \n(3)/(4)=(3 * 4)/(4 * 4)=(12)/(16) \n \n(1)/(2)=(1 * 8)/(2 * 8)=(8)/(16) \n \n(9)/(16) \n \n8<9<10<12 \Rightarrow (8)/(16)<(9)/(16)<(10)/(16)<(12)/(16) \Rightarrow (1)/(2) < (9)/(16) < (5)/(8) < (3)/(4)

In ascending order:
\boxed{(1)/(2), (9)/(16), (5)/(8), (3)/(4)}
(5)/(8)=(10)/(16)\n(3)/(4)=(12)/(16)\n(1)/(2)=(8)/(16)\n\n\Downarrow\n\n\boxed{(1)/(2)<(9)/(16)<(5)/(8)<(3)/(4)}

The sequence of letters in a congruence statement is important: it tells you the corresponding parts.

A triangle, such as ΔCAT, is named using the names of its vertex points. When it is said to be congruent to ΔDOG, it means these correspondences (and congruences) exist:

  • angle C to angle D . . . . . first letters correspond
  • angle A to angle O . . . . . second letters correspond
  • angle T to angle G . . . . . third letters correspond
  • segment CA to segment DO . . . . . named by 1st & 2nd letters
  • segment AT to segment OG . . . . . named by 2nd & 3rd letters
  • segment CT to segment DG . . . . . named by 1st & 3rd letters
