NCERT Books for Class 11 Economics is **one of the best study materials while preparing for the exam**.

UPSC Books from NCERT for General Studies Paper III:

For Economics: **Reference of class 9 to 12** NCERT books for IAS should be ideal, but if you are familiar with the subject, class 11 and some chapters in class 11 and class 12 (micro + macro) would be sufficient.

Root 2 is an irrational number as it cannot be expressed as a fraction and has an infinite number of decimals. So, **the exact value of the root of 2 cannot be determined**.

So square root of 2i is **±(1+i)**. Was this answer helpful?

Two figures are considered to be "similar figures" **if they have the same shape, congruent corresponding angles (meaning the angles in the same places of each shape are the same) and equal scale factors**. Equal scale factors mean that the lengths of their corresponding sides have a matching ratio.

In geometry, when two shapes such as triangles, polygons, quadrilaterals, etc have the same dimension or common ratio but size or length is different, they are considered similar figures. For example, **two circles (of any radii) are of the same shape but different sizes because they are similar**.

Writing Similarity Statements to Match Similar Sides and Angles: Vocabulary. Similar Triangles: **Two triangles are called similar triangles if corresponding angles are congruent, and the ratios of corresponding sides are constant**. Congruent Angles: Two angles are called congruent if they have the exact same measure.

The transformation matrix is **found by multiplying the translation matrix by the rotation matrix**. We use homogeneous transformations as above to describe movement of a robot relative to the world coordinate frame.

With the AA rule, **two triangles are said to be similar if two angles in one particular triangle are equal to two angles of another triangle**.

Here, the term "imaginary" is used because there is no real number having a negative square. There are two complex square roots of −1, namely **i and −i**, just as there are two complex square roots of every real number other than zero (which has one double square root).

The square root of 1 value is: **√1 = 1**. As 1 is a real number and the square of any number is positive, we can assume that the square root of 1 is 1 itself.

Qualitative data is distinguished by attributes that are not numeric and are used to categorise groups of objects according to shared features. Qualitative research is **a scientific method of observation to gather non-numerical data**.

The real roots are **expressed as real numbers**. Suppose ax^{2} + bx + c = 0 is a quadratic equation and D = b2 – 4ac is the discriminant of the equation such that: If D = 0, then the roots of the equation are real and equal numbers.
