Gan fod y pos hwn wedi ei lunio gyda meddalwedd a gynlluniwyd yn arbennig i gynhyrchu ffeiliau pdf yn unig o ddarnau a datrysiadau'r pos, rydym ni wedi sefydlu'r dudalen hon i'r rhai sy'n dibynnu ar raglenni darllen sgrin.
Mae'r pos hwn yn cynnwys 24 triongl hafalochrog gyda gwahanol hafaliad ar bob ochr. Er mwyn sicrhau bod y pos yn bosib bydd angen i chi labelu'r ochrau'n glocwedd yn nhrefn a, b ac c. Gan mai trionglau hafalochrog yw'r rhain, does dim gwahaniaeth pa un yw'r ochr gyntaf (neu 'ochr a').

Mae'r ateb i'r pos hwn yn golygu creu hecsagon y gwerth yr ochrau sy'n cyffwrdd yr un fath, sef x. Cliciwch ar y botwm isod er mwyn dadlennu'r ateb ar ôl i chi orffen neu os ydych chi'n hollol sownd.
Dylai'r hecsagon terfynol gynnwys y trionglau yn y trefniant isod. Fodd bynnag, bydd angen i chi gyfrifo eu cyfeiriadaeth o hyd.
