Suppose, you are attending an exam where there are 9 multiple choice questions with 3 options in each. A question can have multiple correct answers, and in that case, you
have to check all of the correct answers to get the question right.
a. What is the probability that you’ll get exactly 6 of the questions right?
b. What is the probability that you’ll get at most 6 of the questions right?

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
