Circles Class 9 Maths Handwritten Notes

These Circles handwritten notes are a topper's clear revision of the fifth chapter of the new Ganita Manjari book. The Class 9 Maths Handwritten Notes Chapter 5 Circles fit every theorem, diagram, and solved example onto a few pages, written by hand just as you would set it out in the exam.

• What you get: parts of a circle, chord theorems, arc angles, and cyclic quadrilaterals, all in clear handwriting.
• Colour-coded: new sub-topics in red, each theorem in a hand-drawn box, and examples in blue.
• Why by hand: writing each theorem out by hand helps the proof stay in your memory before a test.

These are a topper's own handwritten revision notes for the 2026-27 Ganita Manjari book, matched line by line to the current NCERT chapter.

Why Use Handwritten Notes for Class 9 Maths Circles?

Circle theorems are best learnt with a clear diagram beside each rule. The Class 9 Maths Handwritten Notes Chapter 5 Circles show one theorem per line with its figure, so each result stays clear. You revise the full chapter in one sitting without flipping through the textbook.

• Each theorem, like the angle in a semicircle, sits in its own hand-drawn box.
• A neat circle is drawn next to every rule it proves.
• Red sub-headings split the chapter into short, easy parts.
• The wording is plain, like a senior showing you the proof.

What's Inside the Circles Handwritten Notes PDF

The PDF runs to 22 pages of neat, hand-written revision. It moves from the parts of a circle to chord theorems, arc angles, and cyclic quadrilaterals, with a solved example after each idea. The colour code below tells you what each mark means.

• Red: new sub-topic headings, like Chords or Cyclic Quadrilaterals.
• Boxes: each theorem and key formula, such as the chord length rule, drawn by hand.
• Blue: solved examples and the angles worked out in them.

Circles Diagrams and Formula Boxes Drawn by Hand

Circles is a diagram-heavy chapter, so the notes lean on clear hand-drawn figures. You will find these drawn out step by step:

• A labelled circle showing the centre, radius, chord, arc, and segment.
• The perpendicular from the centre bisecting a chord.
• The central angle drawn as double the angle at the circle.
• The angle in a semicircle shown as a right angle.
• A cyclic quadrilateral with its opposite angles marked as supplementary.

Last-Minute Revision with These Circles Notes

The night before your exam, the Class 9 Maths Handwritten Notes Chapter 5 Circles work as a quick skim. Every boxed theorem and red heading is a checkpoint, so you can cover the whole chapter in well under an hour.

• Name the parts of a circle from the labelled figure.
• Recall that equal chords are equally far from the centre.
• Say the central-angle rule out loud.
• Use the semicircle right-angle result on one quick sketch.
• Check the opposite angles of a cyclic quadrilateral.
• Glance at the common-mistake note before you close the notes.
