2 any kind of two angle whose sum is 180 degrees. Supplementary angles
3 70+x=180 x=110 Example:
4 complementary Angles any kind of two angles whose amount is 90 degrees.
5 Example: x+(x+30)=90 2x+30=90 2x=60 x=30
6 two angles throughout from each other on intersecting lines. Lock are always congruent! Vertical angle
7 Examples: b= ____ degrees
8 adjacent Angles 2 angles the are next to each other and share a typical side.
9 Example: typical side
10 direct Pair two angles that are surrounding and supplementary. They type a right line!
11 Example: 9x+3x=180 12x=180 X=15

2-5 Proving angles Congruent
Adjacent, Vertical, Supplementary, and also Complementary Angles
Lines, Segments, and Rays. Line A heat is perfectly straight and also extends forever in both directions. Any two clues on the line deserve to be used to name.
You are watching: 2 angles whose sum is 180 degrees
Standard 2.0, 4.0. Angles developed by opposite rays.
Warm Up:. Direct Pair I: 2 angles that share a usual vertex and also together make a right line (180°). M: What is the missing measure?
PARALLEL LINES and TRANSVERSALS.
Section 2.7 PROVE edge PAIR RELATIONSHIPS. In this section… we will proceed to look in ~ 2 shaft proofs The proofs will describe relationships v angles.
Angle Relationships section 1-5 adjacent angles angle in the same plane that have a typical vertex and also a common side, but no typical interior points.
Geometry ar 1.6 distinct Angle Pairs. Two angles are nearby angles if 2 angles space vertical angle if.
Angles Acute edge (def)- edge measure less than 90° ideal angle (def)- edge measure= 90° Obtuse edge (def)- angle measure higher than 90° Straight.
Vertical angles – room not adjacent, and their political parties are developed by 2 intersecting present 1 and also 3 space vertical angles 2 and 4 space vertical angles.
Angle relationships Geometry 1.5.
GEOMETRY ar 1.5: edge Relationships. Adjacent angles - 2 angles that lie in the same plane and have actually a typical vertex and also common side, but no common.
1.4 bag of Angles nearby angles- two angles with a typical vertex and common side. (Side through side) straight pair- a pair of adjacent angles the make a.
1.5 exploring Angle Pairs.
2-4 special Pairs of Angles missions -Supplementary angle Complementary angles -Vertical angles.
Chapter 1 - section 3 distinct Angles. Supplementary Angles two or more angles whose amount of their steps is 180 degrees. These angles are also known.
