# True or false parallel lines never intersect or cross each other

The parallelograms are reflections of **each** **other** over the **line** that contains their shared side. Show that m ∠ 2 = 2m ∠ 1. Answer: From FIGURE(1) we get, AB∥DC DC∥EF In the question, it is given that the two given congruent parallelograms are reflections of **each** **other** Hence we can say that the **line** divides the angle into two equal parts.

In terms of art, **line** can be described as a moving dot. **Line** is perhaps the most basic element of drawing. **Line** Variation - the use of a variety of **line** including width, length, texture, thickness, etc. to add interest to a drawing or painting. Length - **lines** can be long or short. Width - **lines** can be wide or skinny.

**Parallel** **Lines** and Transversals. Transversal -. A transversal is a **line** which **intersects** two **or**. more **lines** in a plane. The intersected **lines** do. not have to be **parallel**. **Lines** j, k, and m are intersected by **line** t. Therefore, **line** t is a transversal of **lines** j, k, and m.

**Parallel lines** have the same slope and will **never intersect**.**Parallel lines** continue, literally, forever without touching (assuming that these **lines** are on the same plane).**Parallel Lines** in greater depth. On the **other** hand, the slope of perpendicular **lines** are the negative reciprocals of **each other**, and a pair of these **lines** intersects at 90 .... toward S (analogous to the electric field **lines**). "If two **lines** are drawn which **intersect** a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two **lines** inevitably must **intersect** **each** **other** on that side if extended far enough." (Euclid's version) "The sum of the angles in a triangle is exactly 180 degrees.". Perpendicular **lines** are intersecting **lines**, meaning that they **cross** **each** **other**. **Parallel** **lines**, on the **other** hand, are **lines** that **never** meet, no matter how far they are extended in either direction. 1) Find the first derivative of f (x). 2) Plug x value of the indicated point into f ' (x) to find the slope at x.

About this chapter: Chapter 23 provides minimum requirements for the design of buildings and structures that use wood and wood-based products. The chapter is organized around three design methodologies: allowable stress design (ASD), load and resistance factor design (LRFD) and conventional light-frame construction.In addition it allows the use of the American Wood Council Wood Frame.
