Trousdale County Schools Focused Lesson Plan 2015-16
Teacher: Clinard
Unit Name: Geometric Proof
Unit #: 5
Unit Length: 3 weeks
Week:1/19 – 1/22
Week 2 of 3
Subject: Core Math II
Tennessee State Standard(s) to be taught: (Write the entire standard)

G-CO.9 – Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal
crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a
perpendicular bisector of a line segment are exactly those equidistant from the segment’s endpoints.

G-CO.10 – Prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180°; base
angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third
side and half the length; the medians of a triangle meet at a point.

G.SRT.5 – Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric
figures,.
I Can Statements :

I can find angle measures that will make lines parallel.

I can find measures of interior angles of polygons.

I can find the sum of the interior angles of a polygon.

I can find interior angle measures and exterior angle measure of triangles.

I can use theorems about isosceles and equilateral triangles to solve problems

I can use triangle inequality facts to solve problems.
Accommodations for students, both regular and special populations :

Extra practice time may be given using InteractMath technology online.

One-on-one and/or peer tutoring.

Re-take quizzes on which students perform poorly.
