The best way to gain confidence in mathematics is by studying solved examples. By analyzing how formulas are applied step-by-step, you learn how to tackle complex questions in your homework and exams. Let's walk through standard worked examples for Class 9 Triangles.

Step-by-Step Solved Problems

Example 1: Triangle Side Check

Question: Can a triangle be constructed with sides 3 cm, 4 cm, and 8 cm?

Worked Solution Steps:

  1. Apply side inequality sum rule: a + b > c.
  2. Evaluate smallest sides sum: 3 + 4 = 7.
  3. Compare with third side: 7 < 8.
  4. Since sum does not exceed third side, it is impossible.
Final Answer: No

Self-Practice Method

When studying these examples, cover the solution with a sheet of paper and attempt to solve the question on your own. If you get stuck, reveal the steps one by one to identify where your logic deviated. This active recall method builds long-term problem-solving skills.
