đ Angles are formed by lines in the same plane.

|| Parallel lines never cross, even if they extend infinitely.

âī¸ When lines are no longer parallel, they intersect at a specific point.

đ Angles are formed when lines intersect, and they can be named based on the points used to make them.

đ A shorthand notation, using the angle symbol, can be used to name angles instead of writing the word 'angle' repeatedly.

đ Angles can be visualized as the spaces or shapes formed between intersecting lines.

đ Rotating a line segment creates an arc, which represents an angle between two positions.

đĄ Angles can be represented by an arc with a letter, such as Angle A or Angle B.

â Perpendicular lines form angles that look like a plus sign.

âĄī¸ Perpendicular lines form right angles, which are angles that have a little square symbol to represent them.

đ°ī¸ Rotating a ray to the right creates an angle that is smaller than a right angle, called an acute angle.

âŠī¸ Rotating a ray to the left creates an angle that is larger than a right angle.

đ There are three main kinds of angles: right angles, acute angles, and obtuse angles.

âšī¸ A straight angle is formed when two rays point in opposite directions, creating a straight line.

đ When a right angle or straight angle is divided by a third ray, complementary angles are formed.

đ Complementary angles form a right angle.

đ Supplementary angles form a straight angle.

đ Parallel lines never cross, while intersecting lines form angles.

đ There are different types of angles, such as acute, obtuse, straight, complementary, and supplementary.

đ An acute angle is smaller than a right angle, an obtuse angle is bigger than a right angle, and a straight angle is formed by two rays pointing in opposite directions.

đ Complementary angles add up to form a right angle, and supplementary angles add up to form a straight angle.
