2. Find the size of a missing angle in a triangle, and a quadrilateral, using the information given. Show your work.
The sum of the angles of a triangle equal 180̊. The sum of the angles of a quadrilateral equal 360̊, in a parallelogram the corresponding angles equal 180̊ and opposite angles are congruent.

3. Determine the measure of third angle of a triangle from the information given and draw the triangle. Show your work.
The sum of the angles of a triangle equal 180̊.

4. Given the size of one angle of a rhombus be able to sketch it and explain how you found the missing angle sizes using the properties of a the rhombus.
The sum of the angles of a quadrilateral equal 360̊, the corresponding angles equal 180̊ and opposite angles are congruent.

5. Draw the various cross-sections of  a cylinder, square based pyramid and equilateral triangular prism as given.

6. Draw and label an acute angle, obtuse angle, and reflex angle.  Use arcs, arrows, label as acute, obtuse, or reflex
an acute angle is between 0º and 90º, an obtuse angle is between 90º and 180º, a reflex angle is between 180º and 360º
