What is alternate angle explain with an example?

: 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.

How do you find alternate interior angles?

The alternate interior angles theorem states that, the alternate interior angles are congruent when the transversal intersects two parallel lines. Hence, it is proved. Alternate interior angles can be calculated by using properties of the parallel lines. Two consecutive interior angles are (2x + 10) ° and (x + 5) °.

What is meant by alternate interior angles?

the angles which are inside the parallel lines and on alternate sides of the third line are called alternate interior angles. the angles which are inside the parallel lines and on the same side of the third line are called opposite interior angles.

What are alternate interior angles class 9?

Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but on the opposite sides of the transversal. If these angles are equal to each other then the lines crossed by the transversal are parallel.

Do same side interior angles have the same measure?

The same side interior angles are NOT congruent. They are supplementary. The same side interior angles can be congruent only when each angle is equal to a 90 degree because then the sum of the same side interior angles is equal to 180 degrees.

Does it make sense that same side interior angles are supplementary?

Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

What is the definition of same side interior angles?

Same side interior angles are two angles that are on the interior of (between) the two lines and specifically on the same side of the transversal. The same-side interior angles sum up to 180 degrees. When two parallel lines are intersected by a transversal line they formed 4 interior angles.

Which is the best definition of alternate interior angles?

1 Antithesis of Theorem. If the alternate interior angles produced by the transversal line on two coplanar are congruent, then the two lines are parallel to each other. 2 Co-interior Angles. Co-interior angles are the two angles that are on the same side of the transversal. 3 Co-interior Angle Theorem and Proof. 4 Examples.

How are exponential functions used in real life?

Exponential functions can be applied to various fields such as natural science, commerce and economics. For daily-life phenomena that change over time, we can model them with different exponential functions, which help us study real-life problems by using numerical values.

Which is an example of a co interior angle?

The co-interior angle is also known as the consecutive interior angles or the same side interior angles. If the transversal intersects the two parallel lines, each pair of co-interior angles sums up to 180 degrees (supplementary angles). In the figure, angles 3 and 5 are the co interior angles and angles 4 and 6 are the co-interior angles.

What is the converse of the alternate interior angle theorem?

What is the converse of the alternate interior angle theorem? The converse of alternate interior angle theorem states that “If the alternate interior angles produced by the transversal line on two coplanar are congruent, then the two lines are parallel to each other”
