What are Parallel Lines? - Definition & Concept Definition. Parallel lines are two lines that are always the same distance apart and never touch. In order for two lines to be parallel, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper.

- Corresponding Angles Theorem. Two lines cut by a transversal are parallel if and only if corresponding angles are congruent. Proof: Suppose that L, M and N are three distinct lines. Then we need to prove that M and N are parallel if and only if corresponding angles of the intersection of M and L, and N and L are equal.

The definition of linear pair angles..?!? Best Answer: A linear pair of angles just means two angles that add together to form a line.. See the picture for an example. Another way to say this is the angles are supplementary and add to 180°. The answer to that question should be FALSE, because if two angles are supplementary, they add to 180°. And then by definition they make a linear pair. In other words, supplementary, add to 180° and linear pair are all synonyms for the same thing.

Angles, and More Lines If the slope of one line is -x and the slope of another is 1/x, then -x • 1/x = -1. Perpendicular lines, of course, always form 90° angles. Other terms for perpendicular are: orthogonal, normal, and, of course, right.

- Supplementary angles: Two angles who measures have a sum of 180. and KMH are complementary because they add up to 180 degrees, which is a straight line. is a straight line. Although not pictured, supplementary angles do not need to be adjacent. Vertical angles: Two angles whose sides are opposite rays. The vertical (opposite) angles are congruent. The example below shows two sets of vertical angles, 1 and 3, 2 and 4.

Trapezoid Bases - The two parallel lines are called the bases. The Legs - The two non parallel lines are the legs. Example 1 of legs and the Bases Example 2 of legs and the Bases. The angles on the same side of a leg are called adjacent angles such as $$\angle A $$ and $$ \angle D $$ are supplementary.

- Parallel Lines:Denition: We say that two lines (on the same plane) are parallel to each otherif they never intersect each other, ragardless of how far they are extended oneither side. Pictorially, parallel lines run along each other like the tracks of atrain. BCAD Lines AB and CD are parallel to each other.

Perpendicular In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects.A line is said to be perpendicular to another line if the two lines intersect at a right angle.Explicitly, a first line is perpendicular to a second line if (1) the two lines meet; and (2) at the point of intersection the straight angle on one side of the first line is cut by the second line into two congruent angles. line is said to be perpendicular to a plane if it is perpendicular to every line in the plane that it intersects. This definition depends on the definition of perpendicularity between lines.

14 Side Effects of Amoxicillin There are 14 known side effects for amoxicillin (Amoxil, Trimox), including: 1  allergic reactions like skin rash, itching or hives, swelling of the face, lips, or tongue. 2  breathing problems.3  dark urine. 4  redness, blistering, peeling or loosening of the skin, including inside the mouth.ost of the time, a negative reaction to a drug is not in fact a drug allergy, because it doesn’t involve the immune system. Though it may seem like an allergic reaction, it is really a non-allergic adverse reaction, and is either an undesired side effect or a sign of drug sensitivity.

What is a linear pair of angles? Best Answer: Linear angles are two adjacent angles at the the intersection of two straight lines. Linear angles add up to 180 degrees (i.e., are supplementary angles). See first source. Vertical angles are two angles opposite to one another at the intersection of two straight lines. Vertical angles are equal to one another (are congruent). See second source. Source(s): http://www.mathwords.com/l/linear_pair_o...

Parallel (geometry) The definition of parallel lines as a pair of straight lines in a plane which do not meet appears as Definition 23 in Book I of Euclid's Elements. Alternative definitions were discussed by other Greeks, often as part of an attempt to prove the parallel postulate.

Line (geometry) Definition of Parallel and Perpendicular Lines. Parallel Lines are distinct lines lying in the same plane and they never intersect each other. Parallel lines have the same slope. In the figure below, lines PQ and RS are parallel and the lines l and m are parallel. Perpendicular lines are lines that intersect at right angles.

Angle Properties, Postulates, and Theorems Converse also true: If a transversal intersects two lines and the interior angles on the same side of the transversal are supplementary, then the lines are parallel. The sum of the degree measures of the same-side interior angles is 180°.

Perpendicular and Parallel Parallel. Lines are parallel if they are always the same distance apart (called equidistant), and will never meet. (They also point in the same direction). Just remember:

- Consecutive Exterior Angles. Consecutive exterior angles are formed when two lines are intersected by a transverse line in a same plane. A transverse is a line that intersects two or more lines in the plane at different points.

Parallel Lines: How to Prove Lines Are Parallel Alternate interior angles is the next option we have. These angles are the angles that are on opposite sides of the transversal and inside the pair of parallel lines. So you will have one angle on one side of the transversal and another angle on the other side of the transversal.

Chapter 7: The Family Law System: Custody and Visitation Bias, Speculation, and the “Best Interest of the Child” Standard. As previously mentioned, family courts use the best interest of the child standard to decide custody matters. Most states have developed their own list of factors to determine which custody arrangement would be in the best interest of the child.
