# let us consider one right angle triangle and write the possible ratios of its sides with respect to its acute angle.
+
# Triangle has 3 sides.Using the sides of triangle,we can have six different ratios.(To write the ratio(fraction)numerator can be written in 3 ways and denominator in 2 ways, both can be written in 3*2=6 ways)

# Identify the name of the ratios in Trigonometry.
