Transformations and Scale Factors

The video tutorial guides students through drawing a parallelogram using given points and then scaling it by a factor of one-half. It covers plotting points J, K, L, M, determining the center of rotation, and performing dilation to calculate new points. The tutorial emphasizes using a ruler for accuracy and provides step-by-step instructions for completing the scaled figure.

What is the task given in the video tutorial?

• Draw a rectangle and apply a scale factor.

• Draw a triangle and apply a scale factor.

• Draw a parallelogram and apply a scale factor.

• Draw a circle and apply a scale factor.

• To indicate a new point

• To mark the center of rotation

What is the significance of the center of rotation in this task?

• It is the point around which the figure is rotated

• It is used to calculate the scale factor

• It determines the size of the figure

• It is the starting point for drawing the figure
