Question
Amit followed the following steps to construct a triangle △MAN such that MA = 4 cm, NA = 7 cm and ∠A = 50∘
Step 1:
Draw a line segment of MA of length 4 cm.
Step 2:
Measure the angle A with your protractor. Make a mark at 50 degrees and draw a line from A passing through the mark.
Step 3:
Mark the intersecting point as N.
Step 4:
Join MN to get the required △MAN.
Which of the step is missing for constructing this △MAN ?

Solution
The correct option is A Draw an arc of 7 cm with A as a Centre.
Since, the above data follows from construction of triangle when two sides and included angle is given.
Following the steps from construction of triangle when two sides and the included angle are given, if we draw an arc of 7 cm with A as a centre after step 3, we can construct a triangle with the given measurements.
