If m∠MLN = 60°, what is the measurement of ∠KLO?
What relationship do ∠KLO and ∠MLN have?
m∠KLO = 60°
Which lines, if any, are perpendicular?
Most people think of perpendicular lines as the opposite of parallel.
The two parallel lines are PQ (also PO or OQ) and KR (also KO or OR) because they form a right angle (∠KOQ).
Is ∠LOQ an obtuse, right, or acute angle? How do you know?
What defines an obtuse, right, or acute angle?
Obtuse angles are angles with measurements greater than 90°. ∠LOQ is an obtuse angle because it contains within it ∠KOQ, which is already a right angle.
What is the measurement of ∠POR?
What information can you draw on to solve this?
m∠POR = 90°
Is ∠LOK an obtuse, right, or acute angle?
What does it look like?
∠LOK is an acute angle because it is less than 90° in measurement.
