If the length of the
sides of a triangle are
different ,it is called
scalene triangle.
Construction of a triangle
when two of its sides and
the included angle are
given
(SAS Triangle Construction)
The lengths of two sides of a
triangle PQR where PR =5 cm,
PQ=3 cm and the included angle
P=700
To construct a triangle with two given
sides and the included
angle.
We first draw a rough sketch
of PQR and indicate the lengths of its
sides and the measure of the included
angle.
From the ray PY, cut off
line segment PQ of length
3cm.
Step:2
At P, draw an angle YPR of
measure 700 using a protractor
Join QR.
Thus , PQR is the
required triangle.

two given angles and the included
side.
