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
For 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.

Measuring Segments and Angles
Examine the concept of angles and segments with high schoolers. They will determine the measures of right, acute, and obtuse angles and then find the length of a segment given an algebraic expression. Finally, they will add angles on their Ti-Nspire according to the angle addition postulate.

Discovering AA Similarity Discovery
Your collaborative learners will create, analyze, and then discover the Angle-Angle criterion for similar triangles, as well as experience many of the math practice standards in a very well-organized lesson. They will explore the Angle-Angle criteria further by finding supporting examples that justify the rule holds true for all types of triangles.

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.
