Warm-up (day 5)
Technology Enhanced Items (TEI) questions will be incorporated into each unit, each assessment & on your Geometry SOL. So the more practice we get, the easier they will be On Google Classroom, you will find a folder with TEI questions from each unit. Please print each of set/unit (you can print more than one question on a page, if you would like) and complete these questions throughout the unit. These questions will be due & graded on the day of each unit test!
p.
When writing the equation of circles…. POOP “pull out opposites when writing the equation”
Use what formula? Midpt of the diameter Midpoint (1, 3) What is the radius of a circle? Use what formula? Distance
Write and graph an equation of a circle with center (2, -3) and radius is 5. (When graphing you must plot at least FOUR points on the circle!)
Write the equation of the circles
Given: (x + 2)2 + (y – 3)2 = 16 1. Identify the center and diameter. 2. Identify at least 5 points on the circle 3. Now, connect Points…. is it a circle? Ellipse?
*Quiz *When you finish, come see me for extra practice with a circle activity
Circle Match Activity (15 minutes) Pick one partner. You objective is to match the circle graph with the Center and radius and the equation. Copy the chart below (one per group) and put your first, last names and block. We will do #9 as a class, make sure you write the answers down.
