99 Problems

SWBAT find rotation images and reflection images in regular polygons. SWBAT determine if a figure has rotation or reflection symmetry. Included are three pages of teacher led notes, one page of individual student practice and a full answer key. It is helpful in this lesson to use tracing paper to help students determine the order of rotation. Have students trace the image and place a dot at one of the vertices. Then, spin the tracing paper while keeping the note paper still beneath. Students wi

Students will be able to complete two-column proofs involving angle pair relationships including the angle addition postulate, angle bisectors, complementary and supplementary angles. Included are three pages of teacher-led notes consisting of 6 proofs as well as a full answer key. Try using the Intro to Proofs: Algebraic Proofs Booklet as an introduction to how proofs flow and a review of the properties of equality before using these notes. The booklet can be found at the following link https:

Students will be able to determine congruent parts of congruent triangles, write congruence statements for pairs of congruent triangles, and use the third angle theorem to show triangles are congruent.

Students will be able to use SSS, SAS and HL congruence theorems to prove that triangles are congruent. Prior knowledge of vertical angles and the reflexive property is necessary for some practice problems. Included are three pages of teacher-led notes, 1.5 pages of individual student practice, and a full answer key.

The students will be able to use ASA and AAS congruence theorems to prove that triangles are congruent. Students should already know how to apply SSS, SAS, and HL triangle congruence, vertical angles, the reflexive property, and angle bisectors as some practice problems include these rules. Included are two pages of teacher led notes, two pages of individual student practice problems and a full answer key.

Students will solve for missing angles using the Triangle Sum Theorem and the Exterior Angle Theorem. Included is a 1.5 page worksheet as well as a full answer key.

Use algebra to introduce proofs to your geometry students! Students should already know how to solve one variable equations. Using a skill they already know to introduce the concept of two column mathematical proofs will help students to understand how a proof flows. This booklet includes one page to show examples of 9 properties of equality including the addition, subtraction, multiplication, division, substitution, distributive, reflexive, symmetric and transitive properties. Following are 5
