What is a transversal
Any line that intersects two or more lines.
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, what is their relationship?
What is supplementary
What is the measure of angle y
58
What are supplementary angles?
Two angles whose measures add up to 180 degrees
Complementary Angles
Two angles whose measures add up to 90
What is the relationship between angles 3 and 6 ?
What are Alternate Interior Angles.
Angle 1 is congruent to angle 5
If parallel lines, then corresponding angles are congruent.
What is the measure of angle x
122
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.
If the measure of angle 4 is 112, what is the measure of angle 6?
What is 68. (same-side interior angles)
The m∠4 + m∠6 =180
If parallel lines, then same side interior angles are congruent.
What is the correct equation to find the value of x
7x-5+5x+19=180
What are vertical angles?
Congruent angles formed by two intersecting lines. These angles are located across from each other.
What is the relationship between angles 5 and 8?
What are Vertical Angles.
∠3 is congruent to ∠6, therefore line a is parallel to line m.
If two lines are cut by a transversal and alternate interior angles are congruent, then the lines are parallel.
What is the value of x
13.8
What are Alternate Interior Angles?
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.
If the measure of angle 2 is 37 degrees, what is the measure of angle 7? What is the angle relationship?
What is 37 and Alternate Exterior.
if <3=<7 is this enough to say the two lines are parallel justify why
yes because if alt. int. angles are congruent then lines are parallel
Find the measure of the missing angle
measure of the missing angle = 8
