  1. Dilating a Quadrilateral - Annie Fetter
    Geometry, difficulty level 3. Given two similar quadrilaterals on a coordinate grid, determine the ratio and center of dilation. ...more>>

  2. A Line of Reflection - Annie Fetter
    Geometry, difficulty level 2. Find the equation of the line of reflection for triangle ABC and its image, A'B'C'. ...more>>

  3. Point P Perambulates - Annie Fetter
    Geometry, difficulty level 3. Find the length of the path of a vertex of an equilateral triangle as that triangle rotates around the inside of a square. ...more>>

  4. The Rolling Triangle - Annie Fetter
    Geometry, difficulty level 3. Equilateral triangle ABC sits on top of unit square DEFG so that AC is coincident with DE. The triangle is rotated around the outside of the square until it returns to the top edge. How far did point A travel? ...more>>
