How Do You Find a Value for x that Makes Two Lines Parallel?
Note:
Got a transversal intersecting two lines? Trying to figure out if those lines are parallel? You could test to see if corresponding angles are congruent. This tutorial shows you how!
Background Tutorials
-
Derive and use the distance, slope, and midpoint formulas to verify geometric relationships, including congruence of segments and parallelism or perpendicularity of pairs of lines
-
What are Parallel Lines?
Lines that are parallel have a very special quality. Without this quality, these lines are not parallel. In this tutorial, take a look at parallel lines and see how they are different from any other kind of lines!

Distinguish between undefined terms, definitions, postulates, conjectures, and theorems
-
What is a Plane?
You can't learn everything about math without seeing planes. Did you know that there are rules for naming a plane? This tutorial introduces you to planes and shows you how to name them. Take a look!

Further Exploration
-
Investigate patterns to make conjectures about geometric relationships, including angles formed by parallel lines cut by a transversal, criteria required for triangle congruence, special segments of triangles, diagonals of quadrilaterals, interior and exterior angles of polygons, and special segments and angles of circles choosing from a variety of tools

How Do You Find Missing Angles in a Transversal Diagram?
Got a diagram of a transversal intersecting parallel lines? Trying to figure out all the angle measurements? Take a look at this tutorial, and you'll see how find all the missing angle measurements by identifying vertical, corresponding, adjacent, and alternate exterior angles!
