Question

Lines l and m are parallel lines cut by the transversal line t. Which angle is congruent to ∠7

Answer 1

congruent angles are of similar measures

congruent angles that are congruent to ∠7:

• ∠6       ( vertically opposite angles )

• ∠3        ( corresponding angles )

• ∠2         ( alternate interior angles )

Answer 2

See how

• <7+<5 are linear pairs
• <5+<3 are also linear pairs

From both

• <7 and <3 are equal(Corresponding angles)

Similarly

• <7 nd <6 are equal (Opposite angles)

And

<6 and <2 are corresponding and equal so

• <7 and <2 are equal
