Question

show that the points ( p, p), (-p, -p), (p√3, -p√3) are the vertices of an equilateral triangle​

Answer 1

Step-by-step explanation:

proveby proving all sides are equal

by using DISTANCE formula =underroot X2-X1 Square + y2-y1 square

AB = 2p underoot 2

AC = 2p underroot 2

BC = 2p underroot 2

hence all sides are equal.

therefore it is equilateral triangle

OR

you can solve by constructing altitude and show that altitude bisects the third side . hence you can prove your answer.

best answer and valid answer is first one.

second is for 1 or 2 Mark's questions.
