Geometry II – Lines, Angles, & Arcs: (With Answer Key) – Humble Math Geometry Workbook (Book 2) – 100 Days of Geometry

This is a beginner’s book for learning about lines, angles, and arcs. (An answer key is included in the back of the book).
Concepts and terminology are gradually introduced. Many illustrations and examples are included.

(A protractor is needed for several of the practice problems.)

Topics Covered:
Lines, Rays, & Line Segments

• Naming lines, rays, and line segments
• Parallel lines
• Intersecting lines

Angles

• Naming angles
• Measuring angles
• Types of angles
• Estimating angle measures
• Drawing angles
• Positive and negative angles
• Rotations

Angles and Polygons

• Triangles
• Quadrilaterals
• Shapes within shapes
• Polygons

Circles, Arcs, Sectors, & Segments

• Circles review
• Arcs
• Sectors & Segments

This is Humble Math’s second geometry workbook, but these geometry books may be completed in any order. (The first geometry book focuses on the topics of area, perimeter, and surface area.)

This Geometry II book contains sections that focus on circles, arcs, sectors, and segments. These sections require the area and perimeter of circles to be calculated. But don’t worry, a “circles review” is included to teach students how to perform these calculations.

Completing the first geometry book may be helpful, but it’s not necessary.
