Breakdown of the Question Types and Their Answers
Each section of the exam posed different challenges. Here is a detailed breakdown of typical questions and their solutions.
Multiple-Choice Questions
These questions tested fundamental concepts quickly. Answers often involved applying formulas, recognizing theorems, or eliminating incorrect options.
Sample question:
What is the measure of an interior angle of a regular pentagon?
Answer: 108 degrees
Explanation:
- Sum of interior angles of a pentagon: (5 - 2) × 180° = 540°
- Measure of each interior angle: 540° / 5 = 108°
Grid-In Questions
These required students to produce numerical answers without options. Accuracy and proper calculation were essential.
Sample question:
Calculate the length of the hypotenuse in a right triangle with legs of 6 and 8.
Answer: 10
Explanation:
- Use Pythagorean theorem: c = √(6² + 8²) = √(36 + 64) = √100 = 10
Open-Ended Questions
These often involved proofs, constructions, or explanations of concepts.
Sample question:
Prove that the base angles of an isosceles triangle are congruent.
Answer:
- In an isosceles triangle, two sides are equal.
- By the Isosceles Triangle Theorem, the angles opposite those equal sides are congruent.
- Therefore, the base angles are congruent.

Common Topics and Their Detailed Solutions
Below, we explore some of the most frequently tested topics, complete with explanations and strategies for solving related questions.
1. Congruence and Similarity of Triangles
Understanding the criteria for triangle congruence (SSS, SAS, ASA, AAS, HL) and similarity (AA, SSS, SAS) is crucial.
Key concepts:
- SSS (Side-Side-Side): If three sides of one triangle are equal to three sides of another, the triangles are congruent.
- SAS (Side-Angle-Side): If two sides and the included angle are equal, the triangles are congruent.
- AA (Angle-Angle): If two angles are equal, the triangles are similar.
- SAS (Similarity): If two sides are proportional and the included angles are equal.
Sample problem:
Given two triangles with sides 3, 4, 5 and 6, 8, 10, determine if they are similar.
Answer: Yes, because the ratios of corresponding sides are equal: 3/6 = 4/8 = 5/10 = 1/2.
Conclusion: The triangles are similar by SSS similarity criterion.
2. Properties of Circles
Questions often involve calculating angles, arcs, and lengths related to circles.
Important formulas and theorems:
- Inscribed angles: Measure half of the intercepted arc.
- Central angles: Measure the same as the intercepted arc.
- Chord properties: Equal chords subtend equal arcs; perpendicular bisectors of chords pass through the center.
Sample problem:
An inscribed angle intercepts an arc of 80°. What is the measure of the inscribed angle?
Answer: 40°
Explanation: Inscribed angle = ½ × intercepted arc = ½ × 80° = 40°.
3. Coordinate Geometry
Questions involve plotting points, calculating distances, midpoints, slopes, and equations of lines.
Key formulas:
- Distance between points:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
- Midpoint:
M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
- Slope:
m = (y₂ - y₁)/(x₂ - x₁)
Sample problem:
Find the length of the segment between points (2, 3) and (5, 7).
Answer:
d = √[(5 - 2)² + (7 - 3)²] = √[3² + 4²] = √[9 + 16] = √25 = 5
