• Decimals: Numbers with a decimal point, like 3.14 (pi) or 2.5.
• Fractions: Numbers representing parts of a whole, like 1/2 (half) or 3/4.

Algebra:

• Basic Algebraic Identities: These are equations that are always true, regardless of the values of the variables involved. For the SSC CHSL exam, you might encounter identities like:
  • (a + b)2 = a2 + 2ab + b2 (squaring a binomial)
  • a2 – b2 = (a + b)(a – b) (difference of squares) These identities can be used to simplify expressions or solve equations.
• Elementary Surds (simple problems): Surds are numbers with a radical (square root) symbol. Elementary surds typically involve only square roots. You might be required to:
  • Simplify expressions with square roots (e.g., combining like terms with radicals).
  • Solve simple equations involving square roots (e.g., finding the value of x in x^2 = 4, which has the solution x = ±2).
• Graphs of Linear Equations: Linear equations represent straight lines. You’ll need to understand how to:
  • Plot linear equations on a graph by identifying the slope and y-intercept.
  • Interpret the slope and y-intercept of a linear equation from its graph.
  • Solve problems involving intersecting lines based on their equations and graphs.

Geometry:

While the syllabus mentions familiarity with basic shapes, let’s delve deeper into some key concepts related to:

• Triangles:
  • Types of triangles (equilateral, isosceles, scalene) based on their side lengths and angles.
  • Calculating the perimeter (total length of all sides) and area of triangles using relevant formulas.
  • Identifying special points within a triangle like centroid (center of gravity), incenter (center of inscribed circle), and circumcenter (center of circumscribed circle).
• Congruence and Similarity of Triangles:
  • Congruent triangles: Triangles with exactly the same size and shape (all corresponding sides and angles are equal).
  • Similar triangles: Triangles with the same corresponding angles but sides in a proportional ratio.
  • Using properties of congruent and similar triangles to solve problems involving side lengths and angles.
• Circles:
  • Understanding key terms like radius, diameter, chord, tangent, and secant related to circles.

  • Identifying properties of tangents (lines that touch the circle at one point only) and their relationship with the radius drawn to the point of contact.
  • Understanding how chords divide circles into segments and their related angles.

Trigonometry (if mentioned):

As mentioned earlier, trigonometry deals with relationships between angles and sides of triangles. For the SSC CHSL exam, you might encounter:

• Trigonometric Ratios: These are ratios of sides in a right-angled triangle (sine, cosine, tangent) used to find missing sides or angles when some information is provided.
• Complementary Angles: Two angles that add up to 90 degrees (e.g., 30° and 60°). Knowing complementary angles can help solve problems involving trigonometric ratios.
• Simple Applications: Focus on basic applications of trigonometric ratios to solve problems related to right-angled triangles. This might involve finding missing side lengths or angles based on the given information and relevant trigonometric ratios.

Statistics and Probability (if mentioned):

  • Histogram: A bar graph that shows the frequency distribution of data points.
  • Frequency Polygon: A line graph connecting the midpoints of the tops of bars in a histogram.
  • Bar Diagram: A chart that represents data using rectangular bars of different heights.
  • Pie Chart: A circular chart divided into slices representing proportions of the whole data.
• Measures of Central Tendency: These are statistical measures that represent the “center” of a set of data. You might encounter:
  • Mean (Average): The sum of all values divided by the number of values.
  • Median: The middle value when the data is arranged in ascending or descending order.
  • Mode: The most frequent value in the data set.
• Standard Deviation: This measures how spread out the data is from the mean. (Not typically required for very basic SSC CHSL exams).
