is the required triangle and is the another required triangle.
Step-by-step explanation:
Given,
≅
And,
⇒

⇒
And, (∵≅)
Following steps:
- Draw a line segments using scale.
- as center as radius draw an arc
- as center as radius draw an arc which cuts the before arc at
- Join
Now, is the required triangle.
- Draw a line segments using scale.
- as center as radius draw an arc
- as center as radius draw an arc which cuts the before arc at
- Join and
Hence, is the another required triangle.

Following steps:
Draw a line segments

XY=5.1 cm using scale.
�
X as center
6
�
�
6 cm as radius draw an arc
�
Y as center
3.9
�
�
3.9 cm as radius draw an arc which cuts the before arc at
�
Z
Join
�
�
�
�
�
�

XZ and YZ
Now,
△

△XYZ is the required triangle.
Draw a line segments
�
�
=
3.4
�
�
DE=3.4 cm using scale.
�
D as center
6
�
�
6 cm as radius draw an arc
�
E as center
3.9
�
�
3.9 cm as radius draw an arc which cuts the before arc at
�
F
Join
�
�
DF and
�
�
EF
Hence,
△
