Answer» Answer: it is a isosceles triangle as BC=CA Step-by-step EXPLANATION: point (-2,0) be B and point (0,2) be C Therefore Using DISTANCE formula AB=√(2+2)^2 + (0-0)^2 AB=√(4)^2 AB=4units BC=√(-2-0)^2 + (0-2)^2 BC=√4+4 BC=√8 BC=2√2units CA=√(2-0) ^2+(0-2)^2 CA=√4+4 CA=√8 CA=2√2units As CA=BC Therefore it is a isosceles triangle |
