Section 1.4 and 1.5 Guided Notes • 1.4 Measure and Classify Angles • Notation review: • Point A Ray AB • Line AB Length of line AB • Segment AB • Congruent- • Angle- • Acute- Obtuse- Right- Straight- • Vertex of an angle- • Congruent angles- • Angle bisector- • Example 1: • Name the three angles in the diagram. • _____ or ______ • _____or ______ • _____ or ______ • Check point: • Name all the angles • in the diagram at the right. • What type of angles do the x-axis and the y-axis form in a coordinate plane?
Protractor Postulate- Example 2: Use a protractor to find the measure of each angle: a) m∠ AOB b) m∠ COD c) m∠ DOF d) m∠ COE Angle Addition Postulate- Example 3: Given that m∠ GFJ = 155°, find m∠ GFH and m∠ HFJ. Checkpoint: 3. Given that ∠VRS is a right angle, find m∠VRT and m∠TRS Example 4: Identify all pairs of congruent angles in the diagram. If m∠P = 120°, what is m∠N? There are two pairs of congruent angles: ∠P ≅ _______, ∠L ≅ _________ Because ∠P ≅ _____, m∠P = ________. So, m∠N = ________.
Example 5: In the diagram at the right, WY bisects m∠ XWZ, and m∠XWY = 29°. Find m∠XWZ. 1.5 Describe Angle Pair Relationships Vocabulary: Complimentary angles Supplementary angles adjacent angles linear pair vertical angles Example 1: Identify complements and supplements In the figure, name a pair of complementary angles, a pair of supplementary angles, and a pair of adjacent angles.
Example 2 Find measures of complements and supplements • Given that ∠1 is a complement of ∠2 and m∠2 = 57°, find m∠1. • Given that ∠3 is a supplement of ∠4 and m∠4 = 41°, find m∠3. • Example 3 Find angle measures • Find m∠BCA and m∠DCA. • Example4 • Two angles form a linear pair. The measure of one angle is 4 times the measure of the other. Find the measure of each angle. • Example 5 Identify angle pairs • Identify all of the linear pairs • and all of the vertical angles • in the figure at the right. • HW: p. 28 5-10, 15-41 odd • p. 38 3-15 odd, 16, 17-33 odd, 39-43 odd
