Two lines intersect to form the angles shown.

Which statements are true?

Select each correct answer.

A. m∠2=80°

B. m∠1=100°

C. m∠3=m∠1

D. ​m∠3=80°

Answer: The answer is -

m∠3=80 degree

sm∠3=m∠1

Step-by-step explanation:

When two lines intersect, the opposite angles are equal. They are called vertical angles. That means for this problem: would be true:

m∠1 = m∠3    

100° + m∠3      →    m∠3 = 80°

Whixh set of ordered pairs defines a nonlinear function.​

Line d is parallel to line c in the figure below.
Parallel lines d and c are intersected by lines q and p to form 2 triangles. At lines d and p, the angle is 2, at d and q, the angle is 1, and at q and p, the angle is 3. At lines c and q, the angle is 4, at p and c, the angle is 5, and the third angle is 6. Which statements about the figure are true?
Select three options.
Vertical angles prove that Angle 2 is congruent to angle 5.
In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
Vertical angles prove that Angle 3 is congruent to angle 6.
The triangles are similar because alternate interior angles are congruent.
In the two similar triangles, Angle 2 and Angle 4 are corresponding angles.
The triangles are similar because the corresponding sides are congruent.
