Question

check whether (5,-2) and (6,4) and (7,-2) are vertices ​

Answer 1

Answer:

in an isosceles triangle, any two or three sides are equal

let the three points P= (5, -2), Q = (6, 4), R = (7, -2)

in order to be isosceles,

either

PQ =PR

or

PQ= QR

or

PR= QR

Step-by-step explanation:

we calculate the value of PQ, QR & PR by distance formula
