Amiya Kumar ✨ Common Geometry Symbols – Visual Guide
Geometry problems in CAT/XAT often rely on interpreting visual cues and standard symbols. Recognizing these helps you solve problems faster and with better accuracy. Below are the most common symbols used in geometry questions:
1. Perpendicular Lines ( ⊥)
If two lines are perpendicular, they meet at a right angle.
\[ AB \perp CD \Rightarrow \angle ABC = 90^\circ \]
2. Parallel Lines ( ∥ )
If two lines never intersect and are equidistant at all points, they are parallel.
\[ l \parallel m \]
3. Equal Angles
Small arcs at the vertex of angles indicate they are equal.
\[ \angle A = \angle B \]
4. Equal Lengths
Tick marks on segments show equality.
\[ AB = CD \]
5. Parallelogram Representation
In parallelograms, opposite sides are both equal and parallel. Symbols are shown using double arrows and equal markings.
💡 Quick Tip for CAT/XAT Aspirants:
Spotting these geometry symbols quickly during mocks or the actual test can save you crucial time and eliminate the need for verbal deductions. Train your eyes to read diagrams like text.
