1.5 Describe Angle Pair Relationships 37 EXAMPLE 4 Identify angle pairs Identify all of the linear pairs and all of the vertical angles in the figure at the right. Solution To find vertical angles, look for angles formed by intersecting lines. c∠ 1 and ∠ 5 are vertical angles. To find linear pairs, look for adjacent angles whose noncommon

EXERCISE 2: Choose the correct answer according to the passage. EXERCISE 3: Complete the sentences by selecting words from Column B in EXERCISE 1. 1. I've decided not to….. the matter just now, but don't think I've forgotten about it.

Angles in a Circle and Cyclic Quadrilateral 19.1 INTRODUCTION You must have measured the angles between two straight lines, let us now study the angles made by arcs and chords in a circle and a cyclic quadrilateral. 19.2 OBJECTIVES After studying this lesson, the learner will be able to : zprove that angles in the same segment of a circle are equal

1-4 Practice C Pairs of Angles Draw your answers in the space provided. 1. Draw two intersecting lines and label the resulting angles with the numbers 1, 2, 3, and 4. 2. Label 1 with x. 1 and 2 are supplementary. Find the measure of 2 and label the diagram. 3. 3 is also supplementary to 2. Find the measure of 3 and label the diagram. 4.

Step 1 Use the fact that the sum of the measures of supplementary angles is 180°. m∠BCE+m∠ECD= 180° Write an equation. (4x+ 8)° + (xSubstitute angle measures.+ 2)° = 180° 5x+ 10 = 180 Combine like terms. x= 34 Solve for x. Step 2 Evaluate the given expressions when x= 34. m∠BCE= (4x+ 8)° = (4 ∙ 34 + 8)° = 144°.

18. Complete the figure at the right to show the following relationship: Lines l, m, and n are coplanar and lie in plane Q. Lines l and m intersect at point P. Line n intersects line m at R, but does not intersect line l. 19. Complete the figure at the right to show the following relationship: Plane R contains lines ⃡ and ⃡ ,
