GCSE Secondary Maths Age 13-17 - Geometry & Measures: Transformations - Explained

The video tutorial covers two main geometry transformations: rotation and enlargement. The first part explains how to rotate a shape 180 degrees about a specific point, highlighting the importance of understanding the center of rotation and the angle. The second part focuses on enlarging a triangle by a scale factor of three, emphasizing the need to calculate new positions by multiplying distances from the center. Both tasks include details on how marks are awarded based on accuracy and understanding of the transformations.

What are the two marks awarded for in the rotation question?

Describe the process of enlarging triangle B by a scale factor of three.

What checks can be performed to ensure the enlargement is done correctly?
