AIM: How can we find the measure of unknown angles using multiple steps? Announcements: HW: 74 wksht (online) Do Now: Here are some line segments. Decide if each of these equations is true or false. Be prepared to explain your reasoning. CD+BC=BD AB+BD=CD+AD AC−AB=AB BD−CD=AC−AB Classwork: Lesson snythesis:
From yesterday... Yesterday we learned that complementary angles are two angles that add to make 90 degrees. We also learned that supplementary angles are two angles that add to make 180 degrees. Today, we worked on some activities to illustrate the idea of vertical angles. Vertical angles are formed when two lines intersect. They are opposite each other and are congruent (of equal measure).

AIM: How can we find measures of unknown angles that are not complementary or supplementary? Announcements: HW: 73 wksht (online) Do Now: Given a and b are numbers, and a+b=180, which statements also must be true? a=180−b a−180=b 360=2a+2b a=90 and b=90 Classwork: Yesterday we learned that complementary angles are two angles that add to make 90 degrees. We also learned that supplementary angles are two angles that add to make 180 degrees. Today, we worked on some activities to illustrate the idea of vertical angles. Vertical angles are formed when two lines intersect. They are opposite each other and are congruent (of equal measure). Resources:
AIM: How can we find measures of unknown angles using supplementary and complementary relationships? Announcements: HW: 72 wksht (online) Do Now: Estimate the measure of each angle. Classwork: Students engaged in paper cutting activities to see supplementary and complementary relationships come to life. We learned that when you cut a right angle into two separate angles, both angles add to make 90 degrees. This is a complementary angle relationship. Therefore, if you know one angle, subtract it from 90 degrees to get the other angle. We also learned that two angles that are joined to make a straight line are supplementary. Therefore, if you know one angle, you can subtract it from 180 to get the other table. Resources:
AIM: How can we find the measure of unknown angles? Announcements: HW: Angle Relationships wksht below Do Now: Which angle is bigger? What angle is obtuse? Classwork: Students worked on how to determine the measure of angles in polygons. Resource
AIM: How can we solve problems that use proportional reasoning?
Announcements: The NYS Math Assessment for 7th Grade will be May 12. Please begin your preparations now. HW: Prepare for the state exam! Do Now: List everything you know about proportional relationships. Classwork: Students worked on proportional relationship situations individually for an extended period of time. After the designated period, they compared their methods and results with their partner. Excellent discussions were had. We discussed key points of interest and disagreement as a class and shared correct responses. Resources
