1) The document introduces basic geometry concepts including types of triangles, how to calculate perimeter and area of parallelograms and triangles, and how to use the Pythagorean theorem. 2) It provides examples of calculating the perimeter and area of different shapes such as a parallelogram with measurements of 5 units by 6 units and a right triangle with sides of 6 units, 3 units, and 6.71 units. 3) The Pythagorean theorem is used to find the missing side of a right triangle when given two other side lengths.
