Applied History refers to the utilization of historical knowledge, methods, and lessons for addressing current challenges. It involves drawing insights from the past to inform decision-making and problem-solving in the present. This approach connects historical lessons with contemporary issues and future planning, making history relevant to modern society.
Applied History bridges the gap between past experiences and present-day challenges. It helps analyze historical events, behaviors, and systems to inform decisions in fields like politics, economy, environment, and urban planning. Understanding patterns of past successes and failures aids in better forecasting and future planning.
Applied History helps policymakers and society avoid repeating past mistakes and use proven strategies to build a sustainable and equitable future. It ensures decisions are informed by the lessons of history.
\[ \text{Applied History = Learning from the Past to Solve Present and Future Problems.} \]
Complete the following concept map :
In the following figure \(\triangle\) ABC, B-D-C and BD = 7, BC = 20, then find \(\frac{A(\triangle ABD)}{A(\triangle ABC)}\). 
The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\)) 
Activity :
r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.
A(P-AXB) = \(\frac{\theta}{360} \times \boxed{\phantom{\pi r^2}}\) = \(\frac{\boxed{\phantom{90}}}{360} \times 3.14 \times 10^2\) = \(\frac{1}{4} \times \boxed{\phantom{314}}\) <br>
A(P-AXB) = \(\boxed{\phantom{78.5}}\) sq. cm.
