Vocabulary Part 1
Any line that intersects two or more parallel lines and forms special angle relationships.
What is a transversal
If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.
What are Co-Interior Angles
Two angles are congruent. The measure of the first angles is 42 degrees. The measure of the second angle is this.
What is 42?
When a transversal cuts two parallel lines, this is how many angle measures you need to know to figure out all 8 angle measures in the figure.
What is 1?
Two angles whose measures add up to 90 degrees
What are Complementary Angles?
What is the relationship between angles 4 and 5?
What are Alternate Interior Angles.
If a transversal cuts two non-parallel lines, at least how many angles do you need to know to figure out all 8 angles in the figure?
What is 2.
When 2 parallel lines are both intersected by a transversal, these angles occupy the same relative position on the top and bottom parallel lines.
What are Corresponding Angles.
A pair of angles that are next to each other and share a common side and vertex.
What are Adjacent Angles?
If the measure of angle 8 is 112, what is the measure of angle 6?
What is 68.
If the measure of angle 1 is "4x-6" and the measure of angle 8 is "122 degrees", what is the value of "x"?
What is 32
Congruent angles that are diagonally across from each other.
What are Vertical Angles.
If two parallel lines are intersected by a transversal these angles are located on the outside of the two parallel lines and on the same side of the transversal.
What are Co-Exterior Angles?
If the measure of angle 3 is "150 degrees" and the measure of angle 6 is "3x", what is the measure of angle 7?
What is 150.
When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.
What are Alternate Interior Angles.
Lines that do not intersect.
What are parallel lines?
If the measure of angle 4 is "8x+35" and the measure of angle 6 is "2x+5", then find the value of "x".
What is 14.
