Worked Solution & Example Answer:Triangles A and B are drawn on a coordinate grid - OCR - GCSE Maths - Question 6 - 2018 - Paper 1
Step 1
Describe fully the single transformation that maps triangle A onto triangle B.
Answer
Triangle A can be transformed into triangle B by applying a reflection across the line y = -x. This transformation effectively flips the triangle over the line, aligning its vertices with those of triangle B.
Step 2
Describe fully transformation T.
Answer
Transformation T involves a rotation of triangle A 90 degrees clockwise about the origin (0,0). This rotation adjusts the orientation of triangle A, preparing it for the subsequent reflection in the line x = 0, which then aligns it correctly with triangle B.
