CCC Kwei Wah Shan College 2025 – 2026 S2 Mathematics Form Test (Chapter 11)

Vocabulary and key geometric concepts based on the CCC Kwei Wah Shan College S2 Mathematics Form Test for Chapter 11.

$$AB \parallel CE$$

The geometric condition in Question 1 stating that line segment $AB$ is parallel to line segment $CE$, where $CDE$ is a straight line.

$x$ (Question 1)

The variable representing the angle value to be found where $\angle ABD = \angle DBE = \angle DEB = x$.

Parallel line condition (Question 2)

The premise that if $a = c$, one must determine which statements regarding $AB \parallel DC$ and angle sums totaling $180^\circ$ are true.

$AB \parallel CD$ (Question 3)

The condition given for straight lines $AED$ and $BEC$ used to calculate side lengths $a$ and $b$ using segments of $8\,cm$, $12\,cm$, $6\,cm$, and $15\,cm$.

$$AOB$$

The configuration in Question 4 that must be proven to be a straight line given angle measures of $59^\circ$ and $31^\circ$ at point $O$.

$BCD$ (Question 5)

A straight line used as a reference to find $\angle BAC$ and to prove that $\triangle ABD$ is a right-angled triangle.

$$DB = DE$$

The property of equality between two line segments in Question 6 used to find $\angle BED$ and prove that $AC \parallel DE$.

$$\triangle ABC \cong \triangle CDA$$

The congruence relationship to be proven in Question 7 given the conditions $AD = BC$ and $\angle BCA = \angle CAD$.

$$\triangle ABC \sim \triangle DEC$$

The similarity relationship to be proven in Question 8 where $ACD$ and $BCE$ are straight lines and side lengths are given as $6$, $9$, $10$, and $15$.
