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 includedangle. We first draw a rough sketchof PQR and indicate the lengths of its sides and the measure of the included angle. P 0 3CM 70 5CM R Q
Step:1 Draw a line segment PR of length 5 cm P R . . 5CM
STEP:3 From the ray PY, cut off line segment PQ of length 3cm. Y y Q Q . 0 0 70 70 R P P R 3CM 5CM
Step:2 At P, draw an angle YPR of measure 700 using a protractor Y 0 70 P R
The measures of to angles of a triangle, A=500, B=700and the included side AB=4cm.
To construct a triangle with two given angles and the includedside. To construct a triangle with two given angles and the includedside. A 0 50 4CM o 70 B C
STEP:1 Draw a line segment AB of length 4cm A B 4cm
At A, draw XAB =500 using a protractor00 STEP:2 X 50 A B 4CM
STEP: 3 .At B, draw YBA=700 using a protractor 4CM Y X . . Y . . X 0 0 0 0 50 50 70 70 A A B B 4CM 4CM
. Let AX and BY intersect at C Thus, ABC is the required triangle.
