Consider Theorem 5.10 about Angle-Side Relationships in Triangles.
Angles: ∠ J, ∠ K, ∠ L
Sides: LK, JL, JK
To find the order of angle measures and sides from smallest to largest, let's look at the given diagram and consider the given measures.
m∠ J= 46, m∠ L= 87
Add terms
LHS-133=RHS-133
Therefore, we see that ∠ J is the smallest angle, followed by ∠ K and then ∠ L.
m ∠ J

Angle-Side Relationships in Triangles |
|
If one angle of a triangle has a greater measure than another angle, then the side opposite the greater angle is longer than the side opposite the lesser angle. |
Now, by this theorem, we will look for the corresponding opposite sides. cc Angle & Opposite Side [0.5em] ∠ J & LK [0.5em] ∠ K & JL [0.5em] ∠ L & JK Therefore, we can list the sides in order from smallest to largest. LK < JL < JK
