Answer 2

$\triangle ABC$ is the required triangle.

Step-by-step explanation:

Given,

Construct a $\triangle ABC$ whose perimeter is $12\ cm$ and whose base angles are $45\ degree$ and $60\ degree$.

Following steps:

• Draw line segments $XY=12\ cm$ using scale.
• Draw $45\ degree$ and $60\ degree$ at point $X\ and\ Y$ using protector.
• Bisect the $\angle X\ and\ \angle Y$ and meet the bisect line at $A$.
• Also bisect the line $AX\ and\ AY$ and this two bisect line meet line $XY$ at $B\ and\ C$
• Join $AB\ and\ AC$

Now, $\triangle ABC$ is the required triangle.
