Notes:An angle is a figure formed by two rays, or sides, with a common endpoint called the vertex (plural: vertices). You can name an angle several ways: by its vertex, by a point on each ray and the vertex, or by a number.

A‐BProblemACheck:
m∠DEG = 115°, and m∠DEF = 48°. Find m∠FEG
m∠DEG = m∠DEF + m∠FEG 115° = 48° + m∠FEG
67° = m∠FEG
∠ Add. Post. Substitute the given values. Subtract 48 from both sides.
Simplify.

m∠XWZ = 121°, m∠XWY = 59°. Find m∠YWZ.
m∠YWZ = m∠XWZ – m∠XWY
m∠YWZ= 121° – 59°
m∠YWZ= 62°
∠ Add. Post.
Substitute the given values.

Notes:Congruent angles are angles that have the same measure. In the diagram, m∠ABC = m∠DEF, so you can write ∠ABC ≅ ∠DEF. This is read as “angle ABC is congruent to angle DEF.” Arc marks are used to show that the two angles are congruent.
Notes:An angle bisector is a ray that divides an angle into two
congruent angles. JK bisects ∠LJM; thus ∠LJK ≅ ∠KJM.
m∠_____+m∠_____=m∠ ___
____+____=____
m∠ ___=m∠___
___=___
A‐BProblemACheck:Step 1 Find x.
m∠JKM = m∠MKL
(4x + 6)° = (7x – 12)° +12 +12
4x + 18 = 7x –4x –4x
18 = 3x 6 = x
Def. of ∠ bisector
Substitute the given values. Add 12 to both sides.
Simplify.
Subtract 4x from both sides. Divide both sides by 3. Simplify.
Step 2 Find m∠JKM. m∠JKM = 4x + 6
= 4(6) + 6
= 30°
Substitute 6 for x.
Simplify.
A‐BProblemBCheck:Step 1 Find x.
m∠JKM = m∠MKL
(2x + 3)° = (7x – 12)° +12 +12
2x + 15 = 7x –2x –2x
15 = 5x 3 = x
Def. of ∠ bisector
Substitute the given values. Add 12 to both sides.
Simplify.
Subtract 4x from both sides. Divide both sides by 3. Simplify.
Step 2 Find m∠JKM. m∠JKM = 2x + 3
= 2(5) + 3
= 13°
Substitute 6 for x.
Simplify.
