Question

the base qr of an equilateral triangle pqr with side 10cm lies along x axis such that midpoint of the base is the origin . then the coordinates of the base qr are​

Answer 1

Answer: Q is (-5,0), R is (5,0)

Step-by-step explanation:

QR's midpoint O (0,0) divides the line so that it lies equally in both sides of the y axis.

QR= 10cm

So QO= OR=5cm

So, Q is (-5,0)

And R is (5,0)

Answer 2

Answer:

Q=(-5,0)

R=(5,0)

Step-by-step explanation:

mid-point(let it be S) of QR is origin.

S=0

QR=10

QS=SR= 1/2 QR

QS=SR=5

QR is on x axis; y=0

so x of Q=-5, y=0

& x of R=5, y=0
