Answer 1

Side lengths of 6ft, 8ft, and 10ft. Also 4cm, 6cm, and 9cm can make a triangle. Angle measures must add up to 180 so anything that doesn’t measure up to 180 is incorrect, 2 side lengths of a triangle have to add up and be greater then third side so if 2 sides aren’t greater then the third side, it isn’t possible for those side lengths to be a triangle

Hope this makes sense
