Chapter 8 : Lines and Angles

What will you learn in this chapter

In this chapter, we will be learning about lines and angles. We will learn how to determine and explain the congruency of line segments and angles. We will also learn how to estimate and measure the size of line segments and angles, and understand how the estimation is obtained.

Next, we will study angles related to intersecting lines. We will learn how to identify, explain, and draw vertically opposite angles and adjacent angles at intersecting lines, including perpendicular lines. We will also learn how to determine the values of angles related to intersecting lines, given the values of other angles.

Lastly, we will explore angles related to parallel lines and transversals. We will learn how to recognize, explain, and draw parallel lines and transversals. We will also learn how to recognize, explain, and draw corresponding angles, alternate angles, and interior angles.

By the end of this chapter, we will have a good understanding of lines and angles and be able to apply our knowledge to solve problems involving them.
