Geometry Unit Test Review BASICS (1 Question) What is a line? arrows on both sides - doesn't end What is a ray? one endpoint and one arrow What is a line segment? has endpoints on both sides ANGLES (3 Questions) What is an acute angle? measures less than 90o What is an obtuse angle? measures more than 90o What is a straight angle? measures exactly 180o What is a right angle? measures exactly 90o

Geometry Unit Test Review TRIANGLES (5 Questions) What is an acute triangle? all angles are acute What is an obtuse triangle? has one obtuse angle What is a right triangle? has one right angle What is a scalene triangle? no sides the same length What is an isosceles triangle? two sides are the same length What is an equilateral triangle? all sides are the same length What do all the angles in a triangle add up to? 180o How do you find a missing angle? 1. add the angles you know 2. subtract the sum from 180o
