Juliana e seus pais saíram atrasados de casa para irem ao cinema, mas, por sorte, conseguiram chegar na hora exata em que o filme começou. Ao lado da bilheteria, havia um relógio que marcava o seguinte horário:

Read this text about Yuri Gagarin.

Yuri was born on March 9, 1934 in Klushino, a small village 100 miles west of Moscow. His father was a cabinetmaker, carpenter, bricklayer, and farmer, and his mother was a milkmaid.

On April 12, 1961 the first earthling escaped the gravity well of planet earth. In the spaceship Vostok 1, Senior Lieutenant Yuri Alexeyevich Gagarin orbited earth one time at an altitude of 187 3/4 miles (302 kilometers) for 108 minutes at 18,000 miles an hour.

Following his return to earth, Yuri's triumphant walk through Red Square in front of a crowd of hundreds of thousands made him more nervous and afraid than his historic flight. As he reached the podium, the awaiting Valya tearfully whispered in his ear, "Our dream has come true, Yuri." Embracing her he replied, "You're a smart girl! Thank you!" [...]

Uma família fez uma festa de aniversário e enfeitou o local da festa com bandeirinhas de papel. Essas bandeirinhas foram feitas da seguinte maneira: inicialmente, recortaram as folhas de papel em forma de quadrado, como mostra a Figura 1. Em seguida, dobraram as folhas quadradas ao meio sobrepondo os lados BC e AD, de modo que C e D coincidam, e o mesmo ocorra com A e B, conforme ilustrado na Figura 2. Marcaram os pontos médios O e N, dos lados FG e AF, respectivamente, e o ponto M do lado AD, de modo que AM seja igual a um quarto de AD. A seguir, fizeram cortes sobre as linhas pontilhadas ao longo da folha dobrada.

Após os cortes, a folha é aberta e a bandeirinha está pronta.

A figura que representa a forma da bandeirinha pronta é
