Curated OER
Creating Parallel Lines and Transversals
Have your class create parallel lines. Students will learn how to identify the different angles created by a parallel line cut by a transversal. Then, they identify and name similar and different angles.
Curated OER
The Ambiguous Case
Students investigate the relationship of triangles with its sides and angles. In this geometry lesson, students create visual on the graphing navigator as they study triangles. They move the sides around to create different angle-side...
Curated OER
Pythagorean Triples
Teach how to solve problems with right triangles. Students use the Pythagorean Theorem to identify missing sides and angles. Then, they will define and use the Pythagorean Triples to solve problems.
Curated OER
Exploring the Hinge Theorem
Students explore the application of Hinge Theorem. In this geometry lesson, students write inequalities, given two sides of a triangle. They solve problems with triangular inequalities using the proper theorem.
Curated OER
Triangle Classification
Students classify different types of triangles. In this geometry lesson plan, students identify and use properties of triangles. They differentiate between isosceles and equilateral triangles.
Curated OER
Hexagon Island
Students identify different polygons. In this geometry lesson, students name polygons using the number of sides. They calculate distance and slopes using the correct formula.
Curated OER
Angle Bisectors
High schoolers identify different angles. In this geometry lesson plan, students identify different properties of triangles. They find the altitude, median and angle bisector.
Curated OER
Introduction to Locus
Students define the five rules of loci. In this geometry lesson, students identify the locus of points that creates a circle. They calculate the distance from a fixed line and point.
