Question
Given: P(0,h), Q(h,0), R(-h,0)
Prove: △ PQR is an isosceles triangle.
Hint:
Use distance formula.
The correct answer is: PQR is an isosceles triangle.
Complete step by step solution:
Here P = (0,h)
Q = (h,0)
R = (-h,0)
Length PQ = 
Length PR = 
Length QR = 
Here length of PQ = PR
⇒PQR is an isosceles triangle.
