• Coordinate geometry (distance formula, midpoint formula, slope)
• Geometric transformations (translations, rotations, reflections, dilations)

Key Concepts and Sample Questions from the 2010-2011 Exam

To better understand what the exam entails, let’s review some typical questions and their solutions, which often serve as the answer key or guide for students preparing for similar assessments.

1. Triangle Congruence and Properties

Question: Given triangle ABC with sides AB = 7 cm, AC = 9 cm, and BC = 10 cm, determine whether triangle ABC is right-angled. Justify your answer.

Answer:

To determine if triangle ABC is right-angled, apply the Pythagorean theorem. Check if the square of the longest side equals the sum of the squares of the other two sides.

• Longest side: BC = 10 cm
• Calculate: \( AB^2 + AC^2 = 7^2 + 9^2 = 49 + 81 = 130 \)
• Compare: \( BC^2 = 10^2 = 100 \)

Since \( 100 \neq 130 \), triangle ABC is not a right triangle.

Conclusion: The triangle is not right-angled.

2. Circle Theorems and Properties

Question: In a circle, an inscribed angle intercepts an arc measuring 80°. Find the measure of the inscribed angle.

Answer:

The measure of an inscribed angle is half the measure of its intercepted arc.

• Intercepted arc: 80°
• Inscribed angle: \( \frac{80°}{2} = 40° \)

Conclusion: The inscribed angle measures 40°.

3. Coordinate Geometry Applications

Question: Find the distance between points P(2, 3) and Q(7, 9).

Answer:

Use the distance formula:

\[

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

\]

Calculate:

\[

d = \sqrt{(7 - 2)^2 + (9 - 3)^2} = \sqrt{5^2 + 6^2} = \sqrt{25 + 36} = \sqrt{61} \approx 7.81

\]

Conclusion: The distance between P and Q is approximately 7.81 units.
