Polygons
In this polygons worksheet, 10th graders identify and name 16 different figures that are related to various types of polygons. First, they label each of the figures shown with polygon or not a polygon. Then, students write the reasons...
Curated OER
Cosine
For this cosine worksheet, 10th graders solve 10 different problems that include various triangles. They determine the cosine of one point in each triangle illustrated. Then, they apply the line segments given to each and solve for the...
Curated OER
Parallel, Intersecting, and Perpendicular Lines
In this geometry lines worksheet, 10th graders solve 9 different problems related to various types of lines found in geometry. They classify each pair of lines shown as either parallel, intersecting, or perpendicular lines.
Curated OER
Measurement
In this measurement worksheet, young scholars measure distance with a provided ruler. Using the provided map scale, students determine the actual distance between objects. They may set up proportions to evaluate each situation.
Curated OER
Basic Geometric Constructions
Students observe and demonstrate a variety of basic geometric constructions using the Triman Safety Compass. Using the compass, they draw circles, bisect a line segment, construct an angle, bisect an angle, copy an angle, and create...
Curated OER
Pythagorean Triples
Middle schoolers investigate the mathematical concepts related to the study of The Pythagorean Theorem. They graph and review how to use a line segment to construct a triangle. Then using the theorem students calculate the length of the...
