Two points a and b are 100 mm part a point c is 75mm from a and 60 mm from b draw an ellipse passing through a b and c?

To draw an ellipse passing through points A, B, and C, you can use the property that the sum of the distances from any point on the ellipse to the two foci (A and B) is constant. Since points A and B are 100 mm apart, they will be the foci of the ellipse. Point C being 75 mm from A and 60 mm from B means it lies on the ellipse. Using this information, you can construct the ellipse by finding points that satisfy the distance property.
