`DeltaABC` एक समबाहु त्रिभुजा हे, बिंदु `P,Q, R` भुजा AB,BC,CA के बिंदु हे, तब

Options

A. PQR must be an equilateral triangle
B. PQ+QR=PR+AB
C. PQR must be a right angled
D. PQR must be a right angled triangle

Answer

C

Explanation

According to question,

Given, P,Q and R the mid points of AB, BC and AC
`PQ||AC` and `PQ=1/2AC`
`PR||BC` and PR `=1/2BC`
`RQ||AB` and RQ = `1/2AB` (mid point threom)
`therefore DeltaPQR` is an equilateral triangle
