<p> Weekly Lesson Plan Grade: 9-11 Class/Period Geometry/ 3rd Teacher: C. Gutierrez</p><p>Objective: SWBAT discover points of concurrancy of angle bisectors, Education CCSSM Addressed perpindicular bisectors, and altitudes of a triangle; to discover the Unit 1: Congruence, Proof, and Constructions concurrance of the medians of a triangle and its application. Cluster: Prove geometric theorems. Language Objective: SWBAT discover pints of concurrancy by using CCSS: G.CO.10 Prove theorems about triangles. Theorems include: measures measurments and geometry tools; to discover the concurrance of medians of interior angles of a triangle sum to 180°; base angles of isosceles throuugh the relationships of length. 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.
