Question

What is Lines And Angles?​

Answer 1

Answer:

Angle. An angle is formed when two lines intersect each other. ... An angle involves two legs and one common vertex at which two lines meet. For example: ∠AOD is formed when line AB and CD intersect with each other. Also, ∠AOD is formed between the leg AO and OD, so we include A, O, and D while naming the angle.

Answer 2

Answer:

Angle. An angle is formed when two lines intersect each other. ... An angle involves two legs and one common vertex at which two lines meet. For example: ∠AOD is formed when line AB and CD intersect with each other. Also, ∠AOD is formed between the leg AO and OD, so we include A, O, and D while naming the angle.

Step-by-step explanation:

Axiom 1: If a ray stands on a line, then the sum of two adjacent angles so formed is 180°. Axiom 2: If the sum of two adjacent angles is 180°, then the non-common arms of the angles form a line. Theorem 1: If two lines intersect each other, then the vertically opposite angles are equal.
