7.3 Construction of Triangles When Some Sides and Angles Are Given | Page 160 | Class 7 | Chapter 7

Описание: In this video, we explain Section 7.3 – Construction of Triangles When Some Sides and Angles Are Given from Chapter 7 – A Tale of Three Intersecting Lines, Class 7 Ganita Prakash (CBSE).

This lesson teaches how to construct a triangle when two sides and the included angle are given. Students learn how to use a ruler and compass to draw accurate geometric figures and understand the importance of angle measurement in triangle construction.

📘 Page 160 – Topics Covered:

▶ Understanding how to construct a triangle using two sides and the included angle
▶ Constructing triangle ABC with AB = 5 cm, AC = 4 cm, and ∠A = 45°
▶ Steps to draw the base, create the angle, and mark the other side
▶ Learning why the included angle is essential for a unique triangle
▶ Strengthening accuracy and geometric reasoning

This lesson helps students visualise how side lengths and angles combine to determine a triangle’s shape — an important concept for all geometric constructions.
