Question

. Name the type of triangle PQR formed by the points (√2,√2);(−√2, −√2) (−√6,√6).

Answer 1

Answer:

Equilateral triangle

Step-by-step explanation:

easy bro by distance formulae

all sides are equal

Answer 2

Equilateral triangle

Step-by-step explanation:

PQ $= \sqrt{ ({2 \sqrt{2} )}^{2} + {(2 \sqrt{2}) }^{2} } = 4$

QR $= \sqrt{ ({ \sqrt{2 } + \sqrt{6} ) }^{2} + { (\sqrt{2} - \sqrt{6} ) }^{2} } = 4$

RP $= \sqrt{ ({ \sqrt{2 } + \sqrt{6} ) }^{2} + { (\sqrt{2} - \sqrt{6} ) }^{2} } = 4$

PQ = QR = RP

Hence ∆PQR is an equilateral triangle
