# Corresponding Angles

Come on friends, today we will know about Corresponding Angles.

## What is Corresponding Angles

A corresponding angle is one that has the same position relative to another angle elsewhere in the figure. In plane geometry, when transversals intersect two lines, corresponding angles are formed. Two angles on the same side of the transversal are congruent or related to each other. There is an exterior angle (outside parallel lines) and an interior angle (inside parallel lines).
Corresponding angles are only one type of pair of angles. The angles which are on the opposite side of the transversal are called alternate angles, You can have alternate interior angles and alternate exterior angles.
Corresponding angles are never adjacent angles. They do not touch, so they can never be consecutive interior angles.

## Corresponding sides

In geometry , tests for congruence and equality include comparison of corresponding sides and corresponding angles of polygons . In these tests, each side and each angle in one polygon is combined with a side or angle in another polygon, taking care to maintain the order of adjacency.

For example, if one polygon has sequential sides a , b , c , d , and e and the other has sequential sides v , w , x , y , and z , and if b and w are corresponding sides, then side a (adjacent to b ) must correspond to either v or x (both adjacent to w ). If a and v correspond to each other, then c corresponds to x ,d corresponds to y , and e corresponds to z ; Therefore i th order element abcde corresponds to i th order element symbol for i = 1, 2, 3, 4, 5 on the other hand, if in addition to b corresponding to w we have c Corresponding to v , then i th element of abcde corresponds to i th element of reverse sequence xwvzy .

Congruence tests seek to have equal lengths of all pairs of corresponding sides, although this is not sufficient to establish congruence, except in the case of a triangle (as exemplified by a square and a rhombus that have the same side length). Is). Similarity tests see if the ratios of the lengths of each pair of corresponding sides are the same, although again this is not sufficient. In any case the equality of the corresponding angles is also necessary; The equality (or proportionality) of the corresponding sides with the similarity of corresponding angles is necessary and sufficient for congruence (or similarity). Related angles as well as related sides are defined as appearing in the same order, for example if a polygon has a lateral sequence. With abcd and another corresponding side sequence vwxyz we have the vertex A which appears between the sides a and b then its corresponding vertex angle V must appear between the sides v and w.

#### What is the definition of corresponding angle?

Corresponding Angle: If any two straight lines are cut by a transversal, then the interior angles on the same side of the transversal and the opposite exterior angles are called corresponding angles.

#### How many degrees is the corresponding angle?

From this given, we conclude that the sum of two adjacent angles so formed is 180°.

#### Which of the following is a pair of corresponding angles?

Detailed Solution. When a transversal intersects two lines, the following properties will help us determine whether the lines are parallel. The pairs of corresponding angles are 2 = 6 and 3 = 7.

#### Who is against Sirsa?

3- Vertically opposite angles – If two lines are called vertically opposite angles. Similarly, and intersect at a point, then and/ is also vertically opposite angles. Linear pair of angles- Two such adjacent angles whose two sides other than the common side are opposite rays are called linear pair of angles.

#### What is a 180 degree angle called?

An angle of 180° is called a straight angle or a straight angle.

#### How many types of angles are there?

1. Zero Angle: – If the inclination between the two rays making an angle is zero, then such an angle is called zero angle.
2. Acute Angle:- An angle which is greater than zero but less than 90° is called an acute angle.
3. Right Angle: – An angle of 90 degrees is called a right angle.

Definition of Right Angle- An angle whose inclination between the two rays forming it is 90° is called a right angle.

1. Obtuse Angle:- An angle which is greater than 90° but smaller than 180° is called an obtuse angle.
2. Straight Angle: – An angle of 180° is called straight angle.

Definition of straight angle – An angle in which the two rays making it are in the opposite direction of each other, is called straight angle.

1. Reflex Angle:- An angle which is greater than 180° but smaller than 360° is called acute angle.
2. Complete angle:- An angle of 360° is called a complete angle.

Definition of perfect angle- If the inclination between the two rays making an angle is 360°, then such an angle is called a perfect angle.

1. Supplementary angle: – If the sum of any two angles is 180°, then it is called supplementary angle.
2. Complementary angle: – If the sum of two angles is equal to a right angle, then such angles are called

How many types of triangles are there on the basis of angles?

You know how to classify triangles on the basis of (i) sides (ii) angles. (i) On the basis of sides: scalene, isosceles and equilateral triangles. (ii) On the basis of angles : acute, obtuse and right angled triangles.

#### How many laws of symmetry of a triangle are there?

Mathematics (i) If the corresponding angles in two triangles are equal, then the triangles are similar. (ii) If the corresponding sides of two triangles are proportional, then the triangles are similar. (iii) If one angle of one triangle is equal to one angle of another triangle and the sides forming those angles are proportional, then the triangles are similar.
