Proof of the Pythagorean Theorem Using TransformationsLesson Planet
9th - 12th CCSS: Designed
Middle and high schoolers construct a triangle using Cabri Jr. They construct squares on each of the legs and hypotenuse of the triangle. Pupils show that the area of the squares on the leg equal the area of the square on the hypotenuse.
Proving Angles Congruent and Developing ProofsLesson Planet
9th - 12th CCSS: Adaptable
Students explore the concept of angles. In this angles lesson, students determine the relationships of vertical, complementary, supplementary, and adjacent angles. Students construct proofs using their Ti-Nspire about vertical angles...
Geometry Scavenger HuntLesson Planet
6th - 11th CCSS: Adaptable
Students participate in a scavenger hunt to find the different attributes of selected objects, to prove the object is a particular shape. Sides, angles, parallel lines, congruent angles, opposite angles, diagonal bisectors, congruent...
Part III: Geometry Semester Review (Median, Angles, Congruence)Lesson Planet
9th - 10th
In this geometry semester review worksheet, students identify similar triangles and write congruence statements. They determine the midpoint of a line, and construct bisectors of a line. Students write proofs, identify lines of symmetry,...
