This comprehensive practice test covers the key concepts introduced in Chapter 1 of your geometry textbook. Designed to help you solidify your understanding and prepare for upcoming assessments, this test focuses on fundamental geometric definitions, postulates, and theorems. Remember to show your work where applicable, as the process is just as important as the answer!
Section 1: Definitions and Basic Concepts (Multiple Choice)
-
Which of the following is NOT a basic undefined term in geometry? a) Point b) Line c) Plane d) Angle
-
Two lines that intersect at a 90° angle are called: a) Parallel lines b) Perpendicular lines c) Skew lines d) Intersecting lines
-
A flat surface that extends infinitely in all directions is called a: a) Point b) Line c) Plane d) Ray
-
What is the term for a portion of a line that extends infinitely in one direction? a) Line segment b) Ray c) Line d) Plane
-
Points that lie on the same line are said to be: a) Collinear b) Coplanar c) Concurrent d) Congruent
Section 2: Working with Angles (Short Answer)
-
Find the complement of a 37° angle.
-
Find the supplement of a 112° angle.
-
Two angles are vertical angles. If one angle measures 6x + 10 and the other measures 4x + 20, find the value of x and the measure of each angle.
-
Explain the difference between acute, obtuse, right, and straight angles. Provide an example measure for each.
Section 3: Segments and Midpoints (Short Answer)
-
Point M is the midpoint of AB. If AM = 5x + 10 and MB = 3x + 18, find the value of x and the length of AB.
-
If point P is located at (-2, 5) and point Q is located at (6, -3), find the coordinates of the midpoint of PQ.
-
Define a line segment and explain how it differs from a ray and a line.
Section 4: Problem Solving (Word Problems)
-
Two angles form a linear pair. One angle is twice the size of the other. Find the measure of each angle.
-
Three points, A, B, and C, are collinear. If AB = 8 cm and BC = 12 cm, what is the minimum possible length of AC? What is the maximum possible length? Explain your reasoning.
