Äkki siin leidub kedagi, kes oskaks aidata mul lahendada paari matemaatika ülesannet :

2) Täisnurkse trapetsi sisse on joonestatud ringjoon. Selle ringjoone keskpunkt asetseb trapetsi haara otspunktidest vastavalt 2 cm ja 4 cm kaugusel. Leidke trapetsi pindala.

 

3) Ringjoone raadius on 13 cm ja selle ringjoone sees on võetud punkt M, mis asub 5 cm kaugusel selle ringjoone keskpunktist. Läbi punkti M on tõmmatud kõõl AB=25 cm. Kuidas jaotab punkt M selle kõõlu ?

 

4) Nelinurga ümber joonestatud ringjoone diameeter on selle nelinurga üheks diagonaaliks. Tõestage, et nelinurga vastaskülgede projektsioonid teisele diagonaalile on võrdsed.

See on juba kolmas teema sinu poolt nii lühikese aja jooksul. Kas sa tõesti arvad, et ma peangi sul hakkama neid ülesandeid lahendama? Koolis käid ikka sina.

 

Ürita lahendada ja kui sa mulle lahenduskäigu ette tood ning seal küsid üle, mis õige ja mis vale, siis võin sind juhendada. Niisama ma ei hakka sul neid ülesandeid järjest ära tegema.
