Solving
the right triangle |
To solve a right triangle means to find all unknown sides and angles using its
known parts. |
While solving a right triangle we use
Pythagoras’ theorem and trigonometric functions of an
acute angle depending
which pair of its parts is given. |
Note, right triangles are usually denoted as
follows; c stands for the hypotenuse,
a
and b
for the perpendicular sides called legs, and a and
b
for the angles opposite to a
and b
respectively. |
There are four basic cases that can occur,
given |
a) hypotenuse and
angle, c) hypotenuse and leg, |
b) leg and
angle,
d) two legs. |
