Example1: ABCD is a cyclic quadrilateral. AB and CD are produced to meet P. If angle ADC =
Solution: First step: Make an appropriate figure using statements provided in questions.
See its very simple question, if you know the properties of geometry. Let's try more examples
Example2: ABCD is a parallelogram and P is any point within it. If area of parallelogram is 20 units, then what will be the sum of areas of triangle PAB and PCD?
Solution: According to the question, figure will be as follows:
Properties for this question:
Given that: Area of parallelogram = 20
i.e. Base times Height = 20
To find = Area of ( PAB +PCD)
Example3: ABCD is a cyclic trapezium with AB parallel DC and AB diameter of circle. If
Solution: According to ques, figure will be as follows:
Example4: Two side of plot measures 30m and 22m and angle between them is
Solution: Figure becomes: Center point of BD = O
ABD is a right angle triangle, therefore, Pythagoras theorem followed.
Similarly, using Pythagoras theorem,
Now, Area of triangles
The value of the operation + in
Angles A and B are vertical angles.
Prove the statements: If n is any odd integer, then
The proof of the given statement.
For the V vector space contains all
