Area of Plane Figures (using Trigonometry & Pythagorean Theorem) -6 Task Cards (3 Problems per Card)

Students will solve problems involving the area of plane figures (triangles, rectangles, parallelograms, rhombi, squares, trapezoids and regular hexagons) with this collaborative activity. The problems require students to use trigonometry, Pythagorean Theorem and Heron’s formula!

There are 6 task cards grouped with 3 problems per card so that students can work in groups of 3 (or 2). Problems include:

1. Finding the area
2. Finding a dimension given the area

Card 1 have problems involving area of triangles, card 2 – area of rectangles, card 3 – area of parallelograms and a rhombus, card 4 – area of squares, card 5 – area of regular hexagons and card 6 – area of trapezoids.

Student recording sheets and full solutions (handwritten clearly) are provided.
