In this midpoint of a line activity, students examine coordinates and determine the midpoint of a line segment.  This three-page activity contains 10 multiple-choice problems.  Answers are provided on the last page.

In this perpendicular bisector activity, students fold paper, according to instructions, to discover the perpendicular bisector of a segment.  They explore the distances from the bisector to the endpoints of a specified...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

In this congruence statements worksheet, 10th graders solve and complete 16 various types of problems. First, they complete each congruence statement listed. Then, students graph each set of points on the coordinate plane provided. They...

In this angle measures worksheet, 10th graders solve and complete 6 different types of problems. First, they find the coordinates of each angle given. Then, students determine if the angles are complementary or supplementary. They also...

In this infinite geometric series instructional activity, 11th graders solve and complete 33 various types of problems. First, they find the sum of the infinite geometric series for each of the given. Then, students find the range of...

In this triangulation worksheet, students solve and complete 11 steps of an experiment to determine the distance to a far away object using triangulation and trigonometry. First, they select a far away object and create a baseline far...

In this midpoint worksheet, students use a number line to find the midpoint of a line segment. Next, they find the midpoint of a line using the coordinate plane. Examples of how to use each method are given at the beginning of the...

In this midpoint worksheet, students answer ten multiple choice and five free-response problems using the midpoint formula.  The solutions are provided.

Young scholars explore the concept of coordinate proofs. In this coordinate proofs lesson, students write coordinate proofs using properties of distance, slope, and midpoint. Young scholars discuss why it is sometimes beneficial to...
