(is this a question i can ask @trabolic? ) the velocity of a train relative to the ground is represented by the distance from a to b in the diagram. the velocity of a ball thrown inside the train at an angle of 66° relative to the train is represented by the distance from b to c. what is the distance from a to c (the velocity of the ball relative to the ground), correct to two decimal places? assume that all the points in the diagram lie in the same plane. a. 21.14 m/s b. 18.03 m/s c. 17.20 m/s d. 15.00 m/s

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.
