Class 5 Maths - TELANGANA
Shapes and Patterns
In the Chapter 'Shapes and Patterns' for Class 5 Telangana (TSBSE) students, learners explore the fascinating world of 2D and 3D shapes, lines of symmetry, and how repeating designs are formed. Students will learn to identify angles (acute, obtuse, and right angles) using paper folding, recognize patterns in numbers and shapes, and understand how tessellations cover a surface without gaps. This chapter builds strong spatial awareness and logical thinking, which are essential foundational skills tested regularly in school assessments and crucial for advanced geometry in later board classes.

Types of Angles
An angle is formed when two rays meet at a common endpoint. A right angle measures 90 degrees, an angle smaller than 90 degrees is an acute angle, and an angle larger than 90 degrees is an obtuse angle.
Line of Symmetry
A line of symmetry is an imaginary line that divides a shape into two identical halves that match up completely when folded along the line.
Tessellation
A tessellation is a pattern of repeating shapes that cover a flat surface completely without any gaps or overlapping, like bathroom floor tiles.
Geometric Patterns
A sequence of shapes, numbers, or symbols that repeat or grow according to a specific rule in a predictable order.

Board Exam Info
In Telangana (TSBSE) Class 5 Mathematics examinations, this chapter typically carries around 6 to 8 marks. Common question types include identifying types of angles in given figures, drawing lines of symmetry for letters or shapes, completing number and shape patterns, and identifying which shapes can tile (tessellate) a floor.
Frequently Asked Questions
What is the difference between an acute angle and an obtuse angle?
An acute angle is smaller than a right angle (less than 90°), while an obtuse angle is larger than a right angle (more than 90° but less than 180°).
How do I find the line of symmetry in a shape?
Imagine folding the shape along a straight line. If both halves fit perfectly over each other without any part sticking out, that fold line is a line of symmetry.
Can all shapes be used for tessellation?
No, only certain shapes like squares, rectangles, and equilateral triangles can tile a floor completely without leaving any gaps or overlapping.
