Angle KMQ and angle RNL are  on apposite sides of the transversal and between above and below (exterior to) the parallel lines, so they are alternate exterior angles.  Theorem - Alternate exterior angles formed by parallel lines and a transversal have the same measure.

Answer: Alternative exterior angle theorem.

Explanation:

Since, here PQ and RS are parallel lines and these lines are cut by the same transversal  KL.

And, According to the Alternative exterior angle theorem, when two parallel lines are cut by a transversal , the resulting alternate exterior angles made by these parallel lines are congruent.

After making the diagram of the above situation, we found that \angle KMQ ( on line PQ) and \angle RNL(on line RS)  are alternative angles made by common transversal KL.

Thus, according to the above theorem they must be equal to each other.

That is, m\angle KMQ=m\angle RNL.

Why did Martin Luther write the 95 theses?
Georgia [21]
The 95 thesis was written to speak out against the wrongdoing of the church and the pope. All of the other answers don’t necessarily make sense, because he did not write it to be famous, to be the pope, etc.

In geometry, how do defined terms and undefined terms relate to each other?
mart [117]
In geometry, definitions are formed using known words or terms to describe a new word. There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane. 

<span>POINT (an undefined term) </span>
<span>In geometry, a point has no dimension (actual size). Even though we represent a point with a dot, the point has no length, width, or thickness. A point is usually named with a capital letter. In the coordinate plane, a point is named by an ordered pair, (x,y). </span>

<span>LINE (an undefined term) </span>
<span>In geometry, a line has no thickness but its length extends in one dimension and goes on forever in both directions. A line is depicted to be a straight line with two arrowheads indicating that the line extends without end in two directions. A line is named by a single lowercase written letter or by two points on the line with an arrow drawn above them. </span>

<span>PLANE (an undefined term) </span>
<span>In geometry, a plane has no thickness but extends indefinitely in all directions. Planes are usually represented by a shape that looks like a tabletop or wall. Even though the diagram of a plane has edges, you must remember that the plane has no boundaries. A plane is named by a single letter (plane m) or by three non-collinear points (plane ABC). </span>

<span>Undefined terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. A line segment is the portion of a line that includes two particular points and all points that lie between them, while a ray is the portion of a line that includes a particular point, called the end point, and all points extending infinitely to one side of the end point. </span>

<span>Defined terms can be combined with each other and with undefined terms to define still more terms. An angle, for example, is a combination of two different rays or line segments that share a single end point. Similarly, a triangle is composed of three noncollinear points and the line segments that lie between them. </span>

<span>Everything else builds on these and adds more information to this base. Those added things include all the theorems and other "defined" terms like parallelogram or acute angle. </span>
