Why do angles 1 and 5 have equal measures?
Angles 1 and 5 constitutes one of the pairs. Corresponding angles are congruent. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6.
What is the corresponding angle of ∠ 4?
∠3 and ∠4 form a straight angle, so∠4=120°.
What is the answer when parallel lines are cut by a transversal?
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
When two angles have equal measures?
Two angles are congruent if and only if they have the same measure.
Which angle is an alternate exterior angle to ∠ 8?
In the figure, we can observe that ∠1 and ∠7 are alternate exterior angles and ∠2 and ∠8 are alternate exterior angles because: Both lie on the exterior side of the lines; and. They are placed on the opposite sides of the transversal.
Why are angles equal?
The corresponding angle postulate states that the corresponding angles are congruent if the transversal intersects two parallel lines. In other words, if a transversal intersects two parallel lines, the corresponding angles will be always equal.
Why do angles 1 and 3 have equal measures?
When two lines intersect at a point, they form two pairs of angles that do not share a side. These pairs are called vertical angles, and they always have the same measure. ∠1 and ∠3 are vertical angles.
Why do vertical angles have the same measure?
Vertical angles are always congruent and equal. Vertical angles are congruent as the two pairs of non-adjacent angles formed by intersecting two lines superimpose on each other.
