Quantitative — Geometry (الهندسة) for the GAT (KSA) Exam

Geometry accounts for approximately 20–25% of GAT Quantitative questions. Key topics include: angle properties (supplementary, complementary, vertically opposite), triangle properties (Pythagoras, special triangles), circle properties (area, circumference, sectors), and coordinate geometry (distance, midpoint, slope).

Locale-specific study guides

Pass-rate data, regulatory context, and study tips for Quantitative — Geometry (الهندسة) all change by candidate locale. Pick your context:

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

!Area formula errors: using diameter instead of radius in circle area formula
!Pythagoras theorem errors: not correctly identifying the hypotenuse
!Coordinate geometry: confusing slope formula direction (Δy/Δx, not Δx/Δy)

Study tips

1Memorize the key geometry formulas: area of triangle (½bh), circle (πr²), trapezoid (½(a+b)h), Pythagoras (a²+b²=c²).
2Draw diagrams for every geometry problem — visual representation prevents errors.
3Review the properties of special triangles: 30-60-90 and 45-45-90 side ratios.

A right triangle has legs of length 3 cm and 4 cm. What is the length of the hypotenuse?
- A5 cmCorrect
- B6 cm
- C7 cm
- D√7 cm
Why this answer?
By the Pythagorean theorem: c² = a² + b² = 3² + 4² = 9 + 16 = 25. Therefore c = √25 = 5 cm. This is the classic 3-4-5 right triangle.
