證明BP=RC
怎樣做?

畀d 提示你地啦
1) 證明 <BOP = 60˚
2) 證明 <BAP = 30˚

我係中一的，諗到少少野，我唔知啱唔啱。

<BAC=30
30+<ABC(90)+<ACB=180(< SUM OF TRIANGLE)
<ACB=30

LINE QC and LINE OR is parallel.

<BOR=90

<ORB=30

so <OBR+90+30=180(< SUM OF TRIANGLE)

<QOR=90

<QOR+<OQC+<ORC+<QCR=360(ALL INTERIOR ANGLES OF A QUADRILATERAL)

90+90+30+<ORC=360

<ORC=150

TRIANGLE AOBA IS AN ISOSCELES TRIANGLE.

LINE AO AND LINE OB IS THE SAME

<AORCA IS A TRAPEZIUM.

LINE AO = LINE RC

LINE BP = LINE RC.

BECAUSE TRIANGLE BOPB IS AN EQUILATERAL TRIANGLE.

LINE AO = LINE OP = LINE BP = LINE BO
