(4)の解き方が理解できません。なぜ⊿OBRと⊿OBPを引く必要があるのか教えて欲しいです🙇‍♂️また扇形ORPは3枚目のようになるのにどうやって求めるのでしょうか??

4-(2019年) 兵庫県 図のように, △ABCは1辺の長さが6cmの正三角形で, 頂点A,B,Cは円Oの周上にあり,点Aを含まない弧 BC 上に点Pがある。さらに,点Bを中心として点Pを通る円 と直線AP の交点のうち, P と異なる点をQとする。 次の問いに答えなさい。 ただし, 円周率はとする。 (1) ∠AOB の大きさは何度か 求めなさい。 ただし, 180度 より小さい角度で答えること。( 度) (2)円〇の半径は何cm か 求めなさい。 ( (3) △ABQ≡△CBP を次のように証明した。 この証明を完成させなさい。 (i)()()( cm) < 証明 〉 B -3000 (i) とにあてはまるものを、あとのアーカからそれぞれ1つ選んでその作りを Ekolo △ABQと△CBP において, 35500 △ABCは正三角形なので, AB = CB......① 2点P,Qは,点Bを中心とする同じ円周上にあるので BQ = BP… ② 一 また,弧 AB に対する円周角は等しいので, ∠APB=∠ACB = 60°.. ・③ ②③より, ∠BPQ=∠BQP = 60° なので, FACE < (i) = 60°となり, ∠CBP = 60° (ii) woont また,∠ABC = 60°より,∠ABQ=60° (ii) BC=000-20 ④ ⑤ より ∠ABQ=∠CBP... ⑥ ① ② ⑥ より 2組の辺とその間の角がそれぞれ等しいので, AABQ = ACBP 8 X100154 ・⑤ .O TA A AX - ALE ア BAC イ APC ウPBQ エ CBQオ OAP OBQ (4) 点Pは点Aを含まない弧BC上を動くものとする。△ABQの面積が最大となるとき、2つ 円の重なった部分の面積は何cm2 か,求めなさい。 (cm²)

It became big news because the birth of a baby panda is an *extremely Actually, that of Tian Bao was only the sixth in Europe in the last 20 years. While its population is slowly increasing, the giant panda remains one of the rarest animals 5 in the world. Therefore, scientists have been doing research on how pandas have babies. So, you may think the scientists working at the Belgium zoo *accomplished the goal of their research. But they have another goal; apart from having done that research, they've been studying panda *poo. Why are they doing that? Bm Dimoda ro Tian Bao's mother Hao Hao and its father Xing Hui live in the same zoo as their baby does. While they enjoy sitting in the sun and eating bamboo, with ow dirg.or the scientist team collects their poo. By studying the poo, the team is aiming to understand how pandas can digest bamboo. rare event. 2 Note In fact, bamboo is receiving a lot of attention in biofuel research these days. 15 It's among the fastest-growing plants on earth, and yet needs the least care. So the plant can become a good source of *renewable energy.
