WOODLAND HILLS SECONDARY
LESSON PLANS
Content Area: Geometry
Length of Lesson: 14 days
STAGE I – DESIRED RESULTS
Lesson Topic (Modules, if applicable):
Relationships in Triangles
Big Ideas:
CC.2.3.HS.A.3
Verify and apply geometric theorems asthey relate
to geometric figures.
Understanding Goals (Concepts):
Bisectors, medians and altitudes; Properties of
inequalities relating to the measure of angles and
sides of a triangle and their applications
Student Objectives (Competencies/Outcomes):
1) Identify and use perpendicular bisectors and
angle bisectors in triangles
2) Identify and use medians and altitudes in triangles
3) Recognize and apply properties of inequalities to
the measures of angles of a triangle
4) Recognize and apply properties of inequalities to
the relationships between angles and sides of a
triangle.
5) Apply the Triangle Inequality Theorem
Essential Questions:
Can you…?
*Identify and use perpendicular bisectors and angle
bisectors in triangles?
*Identify and use medians and altitudes in
triangles?
*Recognize and apply properties of inequalities to
the measures of angles and sides of a triangle?
*Apply the triangle inequality theorem?
*Determine the shortest distance between a point
and a line?
Vocabulary:
Perpendicular bisector, concurrent lines, point of
concurrency, circumcenter, incenter, median,
centroid, altitude, orthocenter.
STAGE II – ASSESSMENT EVIDENCE
Performance Task:
Formative Assessments:
Students will actively participate in mini-lessons, guided and independent
Pre-assessments, open-ended higher-order-thinking questions, think-pairpractice, activities (including authentic problem-solving tasks and vocabulary),
share, graphic organizers, do nows, observation of guided and independent
and group work. Also, students will demonstrate adequate understanding via
practice, brief in-class writing prompts
various quizzes, a writing assignment, and an end-of-chapter test.
STAGE III – LEARNING PLAN
Interventions:
Flexible grouping, students will be encouraged to attend Math Lab and College
and Career Access Center tutoring.
Materials and Resources:
Textbook and notes
