99 Problems

Students who need assistance with using the distance & midpoint formulas find these sheets very helpful. Coded blank boxes show students where to plug in each value and guide them through simplifying the formulas. Try printing the sheets back to back and placing in a page protector sheet. Students can then use a dry erase marker to use the sheet over and over.

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 the isosceles triangle theorem and base angles theorem to solve for variables given expressions representing the sides and angles of an isosceles triangle. Included are two pages of teacher-led notes, two pages of individual student practice, and a full answer key

Students will be able to use angle pair relationships to find angle measurements. Students will use the angle addition postulate as well as the definitions of angle bisectors, complementary and supplementary angles to set up and solve equations that will lead to finding missing angle measurements in a variety of diagrams. Included are three pages of teacher led notes as well as two pages of individual student practice problems as well as a full answer key.

Students will be able to find the midpoint and length of a line segment using the midpoint formula and distance formula. The distance formula will be used to determine if two segments are congruent.

Included are three pages of teacher-led notes and two pages of independent student practice as well as a full answer key. The Distance and Midpoint Formula Plug-in Sheet is helpful for learners who need a bit

The students will be able to prove that triangles are congruent by SSS, SAS, HL, ASA or AAS. Included are four pages of teacher-led notes, three pages of individual student practice, and a full answer key.

Students will be able to find two points on a nondirected line segment that partition the segment into a given ratio. Included are three pages of teacher-led notes as well as one page of student practice problems and a full answer key.

Students will be able to identify, classify, and measure angles.

SWBAT predict and verify the sequence of transformations (a composition) that will map a figure onto another. Included are three pages of teacher led notes, two pages of individual student practice and a full answer key.

Students will be able to find trigonometric ratios Sine, Cosine, and Tangent using right triangles. SWBAT solve problems using trig ratios. Included are two pages of teacher-led notes, 1 page of individual student practice, and a full answer key.

Students practice using the rules of reflection to find image coordinates given a preimage in this Color By Number activity. Included are 10 problems that determine the colors to use in given spaces on the autumn themed image. Answer key included.

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

SWBAT find the slope-intercept equation of parallel and perpendicular lines, including vertical and horizontal lines. Students will graph parallel and perpendicular lines. Included are three pages of teacher-led notes, 2 pages of individual student practice, and a full answer key.

SWBAT construct dilations on the coordinate plane. SWBAT find the scale factor and center of a dilation. Included are four pages of teacher led notes, two pages of individual student practice and a full answer key
