Is 2in the radius? if so, the diameter is 4 in
Incomplete question. I inferred you want to know the properties of parallel and perpendicular lines. Which I provided below.
<u>Explanation:</u>
In geometry, <em>parallel lines </em>are two lines that are <em>always </em><em>drawn at </em>the same distance apart and never touch each other. Parallel lines are usually denoted by the symbol ∥.
Here are some of their properties;
When a transversal intersects two parallel lines:
- usually, the corresponding angles of the lines are equal.
- vertically opposite angles are equal.
- the alternate exterior angles are equal.
<em>Perpendicular lines</em><em> are two lines that </em><em>meet at a right angle (90 degrees) to each other.</em>
<em>Properties: </em>two lines that meet, implies all four angles are right angles.
Factor each number:
14=2*7
35=5*7
7 is a common factor, and no other (except 1), so 7 is the greatest common factor (GCF) of 14 and 35.
I believe that makes the two angles acute, because they are less then 90 degrees.
