Draw two-dimensional geometric shapes using rulers, protractors, and compasses.
The core standards covered in this lesson
7.G.A.2 — Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
7.G.B.5 — Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.
The foundational standards covered in this lesson
4.MD.C.6 — Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

Draw a rectangle with dimensions 3 inches × 5 inches.
Can you draw a different quadrilateral with side lengths 3 in., 3 in., 5 in., and 5 in.? If so, draw the shape and name it.
Draw a segment $${AB}$$ that measures 3 cm. Use a compass to construct two circles:
A triangle has an angle measure of 50°. The two side lengths that form this angle are $$3$$ inches and $$4\frac{1}{2}$$ inches long.
Draw the triangle described above. Then determine the measure of the third side and the other two angles.
