What is the opposite of alternate interior angles?
Alternate interior angles are the angles formed on the opposite sides of the transversal. In other words, when two parallel lines are intersected by a transversal, eight angles are formed….Alternate Interior Angles.

Which of the following is not the property of alternate interior angles?
The sum of the angles formed on the same side of the transversal which are inside the two parallel lines is equal to 180°. 3. Alternate interior angles don’t have any specific properties, in case of non-parallel lines.
Can alternate interior angles be non congruent?
Alternate Interior angles that are opposite each other are congruent (the same measure). Alternate Interior angles that are on the same side of the transversal line are called consecutive interior angles. In the case of non-parallel sides, alternate interior angles have no special properties and are not congruent.
What is the example of alternate interior?
When two lines are crossed by another line (called the Transversal): Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal. In this example, these are two pairs of Alternate Interior Angles: c and f.
What are opposite angles?
Opposite Angles. Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure).
Are vertically opposite angles supplementary?
A pair of vertically opposite angles are always equal to each other. Also, a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees. For example, if two lines intersect and make an angle, say X=45°, then its opposite angle is also equal to 45°.
What is alternative interior angle?
Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.
What is alternate angle example?
When two straight lines are cut by a transversal, then the angles formed on the opposite side of the transversal with respect to both the lines are called alternate angles. The pairs of alternate angles in the above figure are: ∠3 and ∠5. ∠4 and ∠6.
What is alternate angle with example?
Which angle is vertically opposite?
When two lines intersect, the opposite (X) angles are equal. In the diagram above, the two green angles are equal and the two yellow angles are equal. These X angles are called vertically opposite angles because they are opposite each other at a vertex.
What is the definition of alternate interior angle?
Definition of alternate angle : one of a pair of angles with different vertices and on opposite sides of a transversal at its intersection with two other lines: a : one of a pair of angles inside the two intersected lines. — called also alternate interior angle.
