Purple color figure is similar to the original figure.

<u>Solution:</u>

Property of similar polygon:

<em>Similar polygons have same shape, corresponding angles are congruent and the corresponding sides are in the same ratio.</em>

(1) <u>Compare original figure with green color figure:</u>

Angles of the original figure:

37°, 53° and 90°.

Angles of the green color figure:

67°, 23° and 90°

These two angles of the triangles not congruent angles.

Hence these shapes are not similar.

(2) <u>Compare original figure with yellow color figure:</u>

Angles of the original figure:

37°, 53° and 90°.

Angles of the yellow color figure:

67°, 23° and 90°

These two angles of the triangles are not congruent angles.

Hence these shapes are not similar.

(3) <u>Compare original figure with purple color figure:</u>

Angles of the original figure:

37°, 53° and 90°

Angles of the purple color figure:

37°, 53° and 90°

These two triangles have same shape and congruent angles.

Ratio of the sides:

$\frac{3}{6}=\frac{1}{2} , \ \frac{4}{8}=\frac{1}{2} , \ \frac{5}{10}=\frac{1}{2}

These two triangles have same ratio.

Hence these shapes are similar.

Hence purple color figure is similar to the original figure.

Answer: (C) x² - 4x + 5 = 0

<u>Step-by-step explanation:</u>

   x = 2 ± i

⇒ x = 2 + i             and       x = 2 - i

⇒ x - (2 + i) = 0     and        x - (2 - i) = 0

 0 = (x - 2 - i)(x - 2 + i)

     = x(x - 2 + i)   -2(x - 2 + i)   -i(x - 2 + i)

     = x² - 2x +xi   -2x + 4 <u>- 2i</u>   -xi <u>+ 2i</u> - i²

     = x² - 4x + 4 - i²

     = x² - 4x + 4 -(-1)

     = x² - 4x + 5
