Question

Check whether the points P(0,4),Q(-2,0) and R(2,0) are the vertices of and equilateral triangle

Answer 1

Answer:

Step-by-step explanation:

P(0,4),Q(-2,0) and R(2,0)

PQ²=(0+2)²+(4-0)²=4+16=20

QR²=(2+2)²+0=16

PR²=((2-0)²+(0-4)²=4+16=20

We get that

PQ=PR

but QR ≠ PQ

Thus the triangle is not a equilateral triangle
