Question

Hola brainlieans !Here is a challenging question for you







If two angles have a common

vertex and their arms form

opposite rays (Fig. 5.41), Then.

(a) how many angles are formed?

(b) how many types of angles are formed?

(e) write all the pairs of vertically opposite

angles​

Answer 1

Answer:

a) 1 angle is formed

b) for this we need the image

c) for this we need the image

Answer 2

Answer:

A) Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.

...

b) The different types of angles based on their measurements are: Acute Angle - An angle less than 90 degrees. Right Angle - An angle that is exactly 90 degrees.

e) Angles ∠1 and ∠3 form a pair of vertically opposite angles; while angles ∠2 and ∠4 form another pair of vertically opposite angles. Clearly, angles ∠1 and ∠2 form a linear pair. again similarly, ∠2 and ∠3 form a linear pair. Thus, if two lines intersect then vertically opposite angles are always equal.
