This worksheet contains a series of compound figures with combinations of squares, rectangles and triangles for which students must find the area. Involved is addition of areas as well as subtraction of areas.

Students use the triangle sum property, vertical angle equality and equality of alternate interior angles to complete a puzzle diagram. If your class does not yet know that alternative angles are equal, simply mark those angles = before making copies (only a couple are involved). A few basic algebraic equations are necessary to find some angle measures.

This is a worksheet with a series of mini angle puzzles involving triangles, quadrilaterals and parallel lines.
