Any line that intersects two or more coplanar lines.
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 Same Side Interior Angles?
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle
What is 42?
If a pair of adjacent angles formed by intersecting line are linear pairs, this is their relationship
What is supplementary?
If a transversal cuts two parallel lines, I only need to know the value of this number of angles to know all of them.
What is 1?

What are supplementary angles?
Two angles whose measures add up to 90o
What are Complementary Angles?
What is the relationship between angles 4 and 5?
What are Same side interior Angles?
One way to prove that lines are parallel lines is through understanding that corresponding angles are
What is congruent?
The sum of the two acute angles in a right triangle is this value.
What is 90o
If two triangles are similar, their corresponding sides are i
What is proportional?
When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.
What are Corresponding Angles?
A pair of adjacent angles formed by intersecting lines.
What is a Linear Pair?
The measure of angle 8 is 112, so this is the measure of angle 7.
What is 68?
To prove that lines are parallel one must understand that same side interior angles are
What is supplementary?

What is 4x-6=122 +6 +6 4x=128 x=32
Triangle A is similar to Triangle B. If the bases of A and B are 12 and 16 inches, respectively, and the height of A is 18 inches, this is the height of B.
What is 24 inches?
The measure of an exterior angle is equal to the sum of this.
What are remote interior 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 Same Side Exterior Angles?
Angles 1 and 3 are
What are Vertical Angles?
If the measure of angle 2 is 30o , what is the measure of angle 7?
What is 150o?
If the measure of <3 is 150 and the measure of <6 is 3x, this is the value of x7.
What is 10?
Triangles P is dilated by a scale factor of 1.5 to get triangle Q. If the base of P is 10 cm, this is the base of the Q.
What is 15 cm?
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?
These are Coplanar lines that do not intersect.
What are parallel lines?
If the measure of angle 1 is 37, this is the measure of angle 8
What is 143?
The measure of an exterior angle of a triangle is 107o. One remote interior angle measures 72o. This is the measurement of the other remote interior angle.
