Mega Study Guide: Mixed Topics (Lines & Angles; Triangles; Polygons; Rectangles; Central Measures)

Notes

MEGA STUDY GUIDE 5 Exercises per topic, increasing in difficulty! 1. Lines & Angles Quick Review: A Segment has a start and an end (A-B). A Ray has a start but no end (A→). A Line has no start and no end (←A-B→). Angles can be Acute (<90°), Right (=90°), Obtuse (>90°), or Straight (=180°). LEVEL 1: VERY EASY Look at a figure with a dot at A and a dot at B connected by a line that ends right there. What type of figure is this (Line, Ray, or Line Segment)? A: LEVEL 2: BASIC The clock strikes exactly 6:00. The hands form a perfectly straight line. What is this type of angle called and how many degrees does it measure? A: LEVEL 3: INTERMEDIATE Name the following angle: An angle that measures 115°. A: LEVEL 4: HARD Two supplementary angles add up to exactly 180°. If one angle measures 72°, what must the other angle measure to be its supplement? A: LEVEL 5: CHALLENGE In angle ∠PQR, point Q is in the center. What is the correct name for the vertex, and what are the two rays (sides) that form it? A: 2. Classifying Triangles Quick Review: By sides: Equilateral (3 equal), Isosceles (2 equal), Scalene (0 equal). By angles: Acute (all <90°), Right (one =90°), Obtuse (one >90°). LEVEL 1: VERY E...
