3. [1 mark] Parametric Triangle. 3 B1 Here we have an initial triangle AoBoCo a final triangle A1 B1 C1 2 C1 The points A, B and C move between the A-points, the B- points and the C-points in a straight line at constant speed, completing the journey in unit time. C https://www.desmos.com/calculator/daflednj6z CO The initial and the final triangles are both isosceles. Does B this happen again for ABC? Find as many incidents as you A -BO can of isosceles triangles in the journey. The data at the N 3 right will give you a good start in your calculations. A = (1-t) Ao + tA1 = [24] B = (1 -t)Bo + tB1 = ] C = (1 -t)Co+ tc1 = litt] B- A = 1- 2t C - A = 4 B - C = 2t - 1)
