Question
During the construction of a quadrilateral for which 2 sides and 3 angles are known, how is the 4th point plotted?
Answer: Option C
:
C
Suppose, we need to construct a triangle of whose two given sides are 'a' cm and 'b' cm and three given angles are x, y and z.
Step 1:Draw PQ= acm.
Step 2: Construct angle measuring x° at point Q.
Step 3: with Q as centre and radius equal to b cm cut an arc to meet at R.
Step 4: Construct an angle measuring y° at point R.
Step 5: Construct an angle measuring z° at P.
Step 6: The point of intersection of both thelines is the required point. Let this point beS.
Thus, fourth point is plotted using lines made by any two angles.
