Question

In the figure shown, lines f and g are parallel. Select all angles that are congruent to angle 1.

Answer 1

`\\ \sf\longmapsto <1\sim <4(Opposite\:angles)`

`\\ \sf\longmapsto <1\sim <5(corresponding \:interior\:angles)`

`\\ \sf\longmapsto <1\sim <8(<5\sim <8)`

Answer 2

Explanation:

∠1 = ∠4 {Vertically opposite angles}

∠1 = ∠5 {Corresponding angles}

∠1 = ∠8 {Alternate exterior angles}
