A plane B is perpendicular to a plane A if plane B contains a line that is perpendicular to plane A. (Think of a book balanced upright on a level surface.) See Figure 3. Figure 3 Perpendicular planes. Theorem 12: If two planes are perpendicular to the same plane, then the two planes either intersect or are parallel. 3.1 Identify Pairs of Lines and Angles Obj.: Identify angle pairs formed by three intersecting lines. Key Vocabulary • Parallel lines - Two lines are parallel lines if they do not intersect and are coplanar. • Skew lines - Two lines are skew lines if they do not intersect and are not coplanar. • Parallel planes - Two planes that do not intersect are parallel planes.determine which lines, if any, are parallel.

Horizontal or vertical lines only. Expected Identify all of the sets of parallel or perpendicular lines that can be made by joining dots. Most parallel or perpendicular lines are horizontal or vertical. Sep 13, 2012 · We can use the Angle Properties of Parallel Lines to solve geometry questions as shown in the following examples. The steps are basically the same for each question. – Look carefully at the given angle, and one of the unknown variable angles, and see if they form one of the common patterns such as X-Shape, Z-Shape, F-Shape, and C-Shape. Angles and Parallel Lines Algebra and Angle Measures Algebra can be used to find unknown values in angles formed by a transversal and parallel lines. If m ∠ 1 = 3 x + 15, m ∠ 2 = 4 x ∠-5, and m ∠ 3 = 5 y, find the value of x and y. p q, so m ∠ 1 = = m ∠ 2 because they are corresponding angles. m∠ 1 = m ∠ 2 3x + 15 = 4 x y-5 3 x ... Two lines are perpendicular if they intersect in a right angle. The axes of a coordinate plane is an example of two perpendicular lines. In algebra 2 we have learnt how to find the slope of a line. Two parallel lines have always the same slope and two lines are perpendicular if the product of their slope is -1.3.1 Lines and Angles 3.1 Lines and Angles Objective: To Identify relationships between figures in a square To identify angles formed by two lines and a transversal. 3.1 Lines and Angles Vocabulary: 3.1 Lines and Angles Vocabulary Transversal - a line that intersects two coplanar lines at two distinct points. 3.1 Lines and Angles Vocabulary Interior angles - Angles that are in between the ...www.ck12.orgChapter 1.
