Advanced Example 1: Proof Using Parallel Lines

Question

Prove that the sum of the interior angles on the same side of a transversal is less than 180∘180^\circ if the lines are not parallel.

Solution

  1. Given: Two lines l1l_1 and l2l_2, and a transversal tt, such that l1l_1 and l2l_2 are not parallel.
  2. To Prove: ∠1+∠2<180∘\angle 1 + \angle 2 < 180^\circ, where ∠1\angle 1 and ∠2\angle 2 are interior angles on the same side of the transversal.
  3. Construction:
    • Extend l1l_1 and l2l_2 indefinitely to meet at point PP.
  4. Proof:
    • Since l1l_1 and l2l_2 are not parallel, they meet at point PP.
    • In △PQT\triangle PQT, the sum of angles of the triangle is 180∘180^\circ: ∠1+∠2+∠P=180∘.\angle 1 + \angle 2 + \angle P = 180^\circ.
    • Here, ∠P\angle P is a positive angle, so: ∠1+∠2<180∘.\angle 1 + \angle 2 < 180^\circ.
  5. Conclusion:
    The sum of interior angles on the same side of a transversal is less than 180∘180^\circ when the lines are not parallel.
  6. Diagram: Let’s plot this graphically.

Graph Explanation

  • The blue line (l1l_1) and the green line (l2l_2) represent non-parallel lines.
  • The red dashed line is the transversal (tt) intersecting l1l_1 and l2l_2.
  • The purple point is the intersection of l1l_1 and tt, while the orange point is the intersection of l2l_2 and tt.

From the graph:

  • The interior angles formed on the same side of the transversal tt (between l1l_1 and l2l_2) are less than 180∘180^\circ, confirming the proof.

Example 1: Understanding Postulates

Question

Using Euclid’s postulates, prove that:
“A straight line can be drawn from any one point to any other point.”

Solution

  1. Postulate Referenced:
    • Euclid’s First Postulate states, “A straight line can be drawn from any one point to any other point.”
  2. Explanation:
    • Consider two points AA and BB in a plane.
    • According to the postulate, there exists one and only one straight line that passes through both AA and BB.
  3. Diagram:
    Draw a plane with two points labeled AA and BB, and connect them with a straight line.
    This represents the unique straight line as per the postulate.
  4. Conclusion:
    The statement is a direct application of Euclid’s First Postulate.

Example 2: Understanding Axioms

Question

Explain the axiom: “Things that are equal to the same thing are equal to one another.” Illustrate with an example.

Solution

  1. Axiom Statement:
    • This is Euclid’s First Axiom, which states that if two quantities are each equal to a third quantity, they are equal to each other.
  2. Explanation:
    • Let a=ba = b and b=cb = c.
    • Since both aa and cc are equal to bb, it follows that a=ca = c.
  3. Example:
    • Suppose AB=5 cmAB = 5 \, \text{cm}, BC=5 cmBC = 5 \, \text{cm}.
    • Since ABAB and BCBC are both equal to 5 cm, we conclude AB=BCAB = BC.
  4. Diagram:
    Draw a line segment divided into two parts ABAB and BCBC, both labeled 5 cm5 \, \text{cm}.

Example 3: Application of Euclid’s Fifth Postulate

Question

Explain the significance of Euclid’s Fifth Postulate and provide an example.

Solution

  1. Postulate Statement:
    • Euclid’s Fifth Postulate states, “If a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side.”
  2. Explanation:
    • This is the basis for parallel and non-parallel lines.
    • If the sum of the interior angles is less than 180∘180^\circ, the lines will meet on that side.
  3. Example:
    • Consider two lines l1l_1 and l2l_2, and a transversal tt.
    • Measure the interior angles on the same side of the transversal.
      • If ∠1+∠2<180∘\angle 1 + \angle 2 < 180^\circ, the lines l1l_1 and l2l_2 will meet.
  4. Diagram:
    Draw two lines and a transversal, showing interior angles ∠1\angle 1 and ∠2\angle 2.

Example 4: Exam-Style Proof

Question

Prove that:
The sum of the angles in a triangle is 180∘180^\circ.

Solution

  1. Given: A triangle ABCABC.
  2. To Prove: ∠A+∠B+∠C=180∘\angle A + \angle B + \angle C = 180^\circ.
  3. Construction:
    • Draw a line DEDE parallel to BCBC through AA.
    • Extend ABAB and ACAC to meet DEDE.
  4. Proof:
    • By the Alternate Interior Angle Theorem, ∠CAB=∠DAB,∠ACB=∠EAC.\angle CAB = \angle DAB, \quad \angle ACB = \angle EAC.
    • Along the straight line DEDE, ∠DAB+∠BAC+∠EAC=180∘.\angle DAB + \angle BAC + \angle EAC = 180^\circ.
    • Substituting, ∠CAB+∠ABC+∠BCA=180∘.\angle CAB + \angle ABC + \angle BCA = 180^\circ.
  5. Conclusion: ∠A+∠B+∠C=180∘.\angle A + \angle B + \angle C = 180^\circ.
  6. Diagram:
    Draw triangle ABCABC with the parallel line DEDE and the angles marked.
