Unit 8 Review Geometry I can identify types of angles #1 All of the following are examples of what type of angle? Why? Acute angles because they are all less than 90 degrees #2 All of the following angles are what type of angles? How do you know? Obtuse angles because they are greater than 90 degrees but less than 180 degrees #3 What type of angle is shown below? A straight angle because it is exactly 180 degrees #4 What type of angles are shown below? Right angle because they are exactly 90 degrees I can recognize and name lines, segments, rays and angles #6 Name the pictures shown below Ray AB Point A Line segment AB #9 Name this angle. Angle JKL or LKJ OR Angle K #10 What is the vertex of this angle?. 560 ÷ 7 The vertex is at point K where the two rays meet #11 Name this angle. Angle B or Angle ABC or Angle CBA I can recognize and name lines, segments, rays and angles #12 What are 3 ways you can name the two angles below? 1. angle KLM, Angle MLK or angle L angle RTS, Angle STR or angle T I can draw and measure angles #14 What is the measurement of this angle? 1. 50 degrees #15 What is the degree measure of angle DOA? 1. 90 degrees #15 What is the degree measure of angle EOA? 1. 120 degrees I can recognize angle measures in circles What types of angles are shown? Acute angle and right angle I can recognize angle measures in circles Obtuse angle and straight angle I can name triangles by their sides and angles #16 What kind of triangles are shown below?
