4) Um grupo de alunos cria um jogo de cartas, em que cada uma
apresenta uma operação com
números racionais. O ganhador é
aquele que obtiver um MAIOR
resultado da soma de suas cartas.
Quatro jovens ao jogar receberam as
seguintes cartas: O vencedor do jogo
foi:

a) Maria
b) Pedro

d) João
e) Rose

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.

i think it might be a but you might want a second opinion
