Question

Fill in the blanks with similar/ not similar
(iv) Two polygons with same number of sides are_______.if their corresponding angles are equal and corresponding sides are equal.

Answer 1

Let us assume two triangles $△ABC$ and $△DEF$ which are equilateral

Here,

$\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}=\frac{1}{2}$

Hence, corresponding sides are in same ratio

In equilateral triangle all three angles are same that is $60°$

Hence, angles are equal of both $△ABC$ and $△DEF$

Thus, $△ABC$ is similar to $△DEF$
