Answer:

∠1 ≅ ∠2 ⇒ proved down

Explanation:

#12

In the given figure

LJ // WK

∵ LP is a transversal

∠1 and ∠KWP are corresponding angles

∵ The corresponding angles are equal in measures

∴ m∠1 = m∠KWP

∠1 ≅ ∠KWP ⇒ (1)

WK // AP

∵ WP is a transversal

∠KWP and ∠WPA are interior alternate angles

∵ The interior alternate angles are equal in measures

∴ m∠KWP = m∠WPA

∠KWP ≅ ∠WPA ⇒ (2)

From (1) and (2)

∵ ∠1 and ∠WPA are congruent to ∠KWP

∴ ∠1 and ∠WPA are congruent

∠1 ≅ ∠WPA ⇒ (3)

WP // AG

∵ AP is a transversal

∠WPA and ∠2 are interior alternate angles

∵ The interior alternate angles are equal in measures

∴ m∠WPA = m∠2

∠WPA ≅ ∠2 ⇒ (4)

From (3) and (4)

∵ ∠1 and ∠2 are congruent to ∠WPA

∴ ∠1 and ∠2 are congruent

∠1 ≅ ∠2 ⇒ proved
