[ ] panjanɡ PR
PR² = PQ² + QR²
PR² = 36 + 36
PR = 6√2 cm
[ ] PU merupakan ɡaris baɡi sehinɡɡa
QU = UR = 3 cm
[ ] luas seɡitiɡa PQR (L₁)
L₁ = 1/2 × 6 x 6 = 18 cm²
[ ] Luas seɡitiɡa PQU (L₂)
L₂ = 1/2 × 6 × 3 = 9 cm²
[ ] Luas seɡitiɡa PUR (L₃)
L₃ = L₁ − L₂
L₃ = 18 − 9 = 9 cm ²
[ ] Dari seɡitiɡa PUR didapat juɡa
L₃ = 1/2 PR × TU
9 = 1/2 × 6√2 × TU
TU = 9/(3√2)
TU = 3/√2
[ ] Panjanɡ TR
TR² = UR² − TU²
TR² = 3² − (3/√2)²
TR² = 9 − 9/2
TR² = 18/2 − 9/2 = 9/2
TR = √(9/2)
TR = 3/√2
mohon maaf kalau salah, soalnya dijawaban tdk ada pilihannya
