1. Angles Day One and Two
Objective: You will be able to understand and use vocabulary about angles and triangles in your partner groups You will measure angles first with a partner to determine accuracy and then on your own.
Warm-up: What do you remember about angles and triangles? Day One: CW and HW: Vocabulary Cards Day Two CW: Measuring angles and Vocabulary HW: Complete WKSH and Vocabulary

2. Vocabulary Create Flash Cards: Word, Definition, and Drawing
Ray - A part of a line. It has exactly one endpoint Angle - A figure formed by two rays with a common endpoint Vertex - Corner or intersection of geometric points Side - One of the rays forming the exterior of an angle or polygon Right Angle - An angle that measures 90 degrees Acute Angle - An angle that measures less than 90 degrees Obtuse Angle - An angle that measures more than 90 degrees but less than 180 degrees Straight Angle - An angle that measures 180 degrees Complementary Angles - Two angles whose sum is 90 degrees Supplementary Angles - Two angles whose sum is 180 degrees Congruent Angles - Angles that have the same measure Adjacent Angles - Angles that share a vertex and a side but no points in their interiors Vertical Angles - Angles formed by two intersecting lines and are opposite each other. Vertical angles are congruent. Triangle - A three sided polygon Equilateral Triangle - A triangle with three congruent sides Isosceles Triangle - A triangle with two congruent sides Scalene Triangle - A triangle with no congruent sides Right Triangle - A triangle containing a right angle Acute Triangle - A triangle with all angles measuring less than 90 degrees Obtuse Triangle - A triangle containing one obtuse angle

3. Special Angles Day Three
Objective: You will be able to classify and find the measurement of angles using properties of special angles with a partner.
Focus of Vocabulary:
Vertical Angles - Angles formed by two intersecting lines and are opposite each other. Vertical angles are congruent
Adjacent Angles - Angles that share a vertex and a side but no points in their interiors
Complementary Angles - Two angles whose sum is 90 degrees
Supplementary Angles - Two angles whose sum is 180 degrees
Warm-up: Complete 2 CASE21 problems and
