Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms. 2 similar right triangles. Triangle 1 has side length 8, hypotenuse 10, and blank side. Triangle 2 has side length 4, hypotenuse 5, and blank side.
a.
StartFraction 4 Over 10 EndFraction = StartFraction 5 Over 8 EndFraction = two-fifths
b.
StartFraction 4 Over 8 EndFraction = StartFraction 5 Over 10 EndFraction = one-half
c.
StartFraction 10 Over 4 EndFraction = StartFraction 8 Over 5 EndFraction = Five-halves
d.
StartFraction 4 Over 5 EndFraction = StartFraction 8 Over 10 EndFraction = four-fifths
