Customers are used to evaluate preliminary product designs. in the past, 95% of highly successful products received good reviews, 60%of moderately successful products received good reviews, and 10% of poor products received good reviews. in addition, 40% of products have been highly successful, 35% have been moderately successful, and 25% have been poor products. if a product does not attain a good review, what is the probability that it is a poor product?

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.
