segment, based on the undefined notions of point, line, distance along a line, and

figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence

congruent and corresponding angles are congruent; points on a perpendicular bisector

or disprove that a figure defined by four given points in the coordinate plane is a
rectangle; prove or disprove that the point (1, -3) lies on the circle centered at the

Mid-term Final
At the end of this unit, you should be able to
1) know how to set up and solve an equation involving ratios.
2) know how to calculate the geometric mean.
3) know the properties of similar polygons: corresponding angles are congruent but corresponding side
lengths are proportional.
4) know how to set up a proportion to solve the length of a corresponding side or a corresponding angle
in similar polygons
5) know that two triangles are similar if two pairs of corresponding angles are congruent: AA  AA or
AA Similarity Theorem; prove two triangles are similar by AA Similarity Theorem.
6) find the missing angle measure to show that two triangles are similar by AA Similarity Theorem.
7) know that two triangles are similar if three pairs of corresponding sides have the same ratio: SSS
Similarity Theorem; prove two triangles are similar by SSS Similarity Theorem.
8) find the missing length to show that two triangles are similar by SSS Similarity Theorem.
9) know that two triangles are similar if the lengths of two corresponding sides have the same ratio and
the included angles are congruent: SAS Similarity Theorem.
10) find the missing length to show that two triangles are similar by SSS Similarity Theorem.
11) know the relationship between the ratio of the perimeters and the ratio of corresponding sides of
similar polygons, and solve problems involving these ratios.

Common Core Standards Addressed
G-CO.2
Represent transformations in the plane using, e.g., transparencies and geometry
software; describe transformations as functions that take points in the plane as inputs
and give other points as outputs. Compare transformations that preserve distance and
angle to those that do not (e.g., translation versus horizontal stretch).
G-SRT.1
Verify experimentally the properties of dilations given by a center and a scale factor:
a. A dilation takes a line not passing through the center of the dilation to a parallel
line, and leaves a line passing through the center unchanged.
b. The dilation of a line segment is longer or shorter in the ratio given by the scale
factor.
G-SRT.2
G-SRT.3
G-SRT.4
G-SRT.5
G-C.1
G-MG.3
Given two figures, use the definition of similarity in terms of similarity
transformations to decide if they are similar; explain using similarity transformations
the meaning of similarity for triangles as the equality of all corresponding pairs of
angles and the proportionality of all corresponding pairs of sides.
Use the properties of similarity transformations to establish the AA criterion for two
triangles to be similar.
Prove theorems about triangles. Theorems include: a line parallel to one side of a
triangle divides the other two proportionally, and conversely; the Pythagorean
Theorem proved using triangle similarity.
Use congruence and similarity criteria for triangles to solve problems and to prove
relationships in geometric figures.
Prove that all circles are similar.
Apply geometric methods to solve design problems (e.g., designing an object or
structure to satisfy physical constraints or minimize cost; working with typographic
grid systems based on ratios).
Methods of Differentiated Instructions
Revolution K-12, a student-driven online learning platform, is used to differentiate instruction for all
students in class and subject areas.
All students are held to the Common Core-aligned standards. Teacher performs formative assessments
through lessons to check student understanding, including cold-calling, student board work, and exit
tickets. Teacher circulates room to perform further formative assessments and to guide small groups and
individuals.
Lower-performing students are grouped heterogeneously with higher-performing students using
assessment data, interests, and work habits, to encourage student-to-student engagement and learning.
They are also provided guided notes and graphic organizers to build schemas.
English Language Learners are paired with students who are fluent in English, and given extra time.
Vocabulary is pronounced several times and accompanied by alternative words or phrases that are
simplified. Visual aids, including pictures, Smart boards, and manipulatives, help students make clear
connections to the text.
Students with Special Needs are grouped with helpers and given instructions or assessments with
simplified language or extra time. Color-coding on the Smart board help illustrate steps required to solve
a problem. Hands-on activities are provided to help construct student learning.
Gifted/Honor students are given challenge problems during lessons, homework, and summative
assessments, which earn extra credits. They are expected to complete the whole worksheet, and are
given challenge (e.g. open-ended) problems that develop higher-level thinking.
