Description

Quick Overview

A trapezium is defined as a quadrilateral with at least one pair of parallel sides.

Standard

In this section, we explore the characteristics of a trapezium, including its definition as a quadrilateral with one pair of parallel sides, the distinction between trapezium types such as isosceles trapezium, and practical activities to understand their properties.

Detailed

Detailed Summary of Trapezium

In this section, we delve into the concept of a trapezium, which is defined as a quadrilateral with at least one pair of parallel sides. The text illustrates various figures of trapeziums and non-trapeziums, prompting students to engage in discussions about their characteristics. Furthermore, the section introduces the specific case of an isosceles trapezium, where the non-parallel sides are equal in length.

Practical activities facilitate hands-on learning, such as using cut-outs of triangles to form trapeziums and using set-squares to find different configurations of trapeziums. This immersive approach aids students in visualizing and understanding trapeziums' properties and classifications within the broader context of quadrilaterals.

Key Concepts

  • Trapezium: A quadrilateral with at least one pair of parallel sides.

  • Isosceles Trapezium: A trapezium with equal non-parallel sides.
