Geometry In Space
How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the angles in a triangle.

Standardized Geometry Test Practice
In this angles, lines and figures review worksheet, 10th graders solve and complete 33 standardized multiple choice problems. First, they use the Segment Addition Postulate to solve for a variable given an equation for each line. Then, students use the Law of Syllogism and the given statements to write a conditional statement.

Spherical Geometry: A Global Perspective
Students investigate spherical geometry using a globe and an apple. In this spherical geometry lesson plan, students translate Euclidean geometry terms to spherical geometry terms using a globe. They answer 3 questions about spherical geometry and use an apple to represent the globe and they cut spherical 'triangles', they score the 'equator' and they cut circles through the 'poles' of the apple better understand the concepts of spherical geometry.

Similarity and Congruence
Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such as SSS or SAS to prove congruency and similarity.

Segment Addition Postulate
Students create an interactive diagram that supports the Segment Addition Postulate. They draw segment AB with point C and between points A and B. Finally, students find the lengths of and label AC, CB, and AB calculating the length of AC + CB.

How Do You Prove that Two Overlapping Triangles are Congruent?
Given two overlapping triangles with a congruent angle, a common angle, and a congruent side, a simple proof is shown in this video. Using the ASA (angle-side-angle) postulate, the instructor shows how the two triangles are congruent.
