Answer 1

Answer:

AB=4.5

BC=4.5

AC=4.5

it is similar triangle

Answer 2

Given data:

The given triangle $\Delta ABC$ has three equal sides $AB,BC,CA$ of equal length $4.5\:cm$.

Analyzing the triangle:

• Since the three sides are of equal length, $\Delta ABC$ is an equilateral triangle.

• Being an equilateral triangle, each interior angle of it measures $60^{\circ}$

• The perimeter of this triangle is $(3\times 4.5)\:cm=13.5\:cm$

• The area of this triangle is $\frac{\sqrt{3}}{4}\times (4.5)^{2}\:cm^{2}=8.77\:cm^{2}$ (approx.)
