Illustration
Solve the right triangle ABC, if hypotenuse c = 6 and b = 3.
Solution
We have a^{2}=c^{2}  b^{2}\
a^{2}=6^{2}b^{2} \
a^{2} = (6)^{2}  (3)^{2} \
a^{2}=27
(II) Two sides other than hypotenuse being given
Illustration
Solve the right triangle PQR, Given that r = 8,
p = 5.
Solution :
(III) One angle (other than right angle) and its opposite side being
known.
Illustration
Solve triangle LMN, Ð M = 90^{0},
Ð L = 30^{0} and l
= 10
Solution : In triangle LMN, Ð
N = 90^{0}  Ð L \
Ð N = 90^{0}  30^{0} = 60^{0}
(IV) One angle (other than right angle) and its adjacent side is
being given.
