Answer 1

Hi mate hope this will help you..

_____________

Line segment is a right answer...


______________

Answer 2

Option 2 (ANGLE) is the correct answer.

• Consider the given options,

=> Option A: ( Line Segment )

• The length of the line segment changes if the figure is enlarged, the length of the figure varies, hence the two figures will not be congruent.

=> Option B: ( Angle )

• When the angle is enlarged, the angle does not change irrespective of the enlargement.
• Hence, the two figures are congruent to each other irrespective of the enlargement.

=> Option C: ( Triangle )

• When the triangle is enlarged, the side length will be increased, hence the area will be increased.
• Hence, the two figures are not congruent to each other.

=> Option D: ( Square )

• When the square is enlarged, the side length of each side is increased, hence the perimeter and area also changes.
• Hence, the two figures are not congruent to each other.

=> Option E: ( Circle )

• When the circle is enlarged, the radius also changes. The area also changes.
• Hence, the two figures are not congruent to each other.

Hence, Option 2 ( Angle ) is the only figure which is congruent with its enlarged copy.
