What type of angle is 2 and 4?
Vertical Angles – Two angles formed by intersecting lines. They can not be adjacent but are always equal in measure. They are across from one another in the corners of the “X” formed by the lines. In the above picture, angles 1 and 3 and angles 2 and 4 are vertical because they are across from each other.
What type of angles are angle 2 and angle 4?
When two lines intersect at a point, they form two pairs of angles that do not share a side. These pairs are called vertical angles, and they always have the same measure. ∠1 and ∠3 are vertical angles. ∠2 and ∠4 are vertical angles.
What is an angle relationship?
We talk of angle relationships because we are comparing position, measurement, and congruence between two or more angles. For example, when two lines or line segments intersect, they form two pairs of vertical angles.
What are angle pair relationships?
Special angle relationships are formed when two lines intersect, and you can use your knowledge of linear pairs of angles to explore each angle further. Vertical angles are defined as two non-adjacent angles formed by intersecting lines. You can use that information to find the measurement of all of the other angles.
When are two angles supplementary to each other?
1 Two angles are supplementary if the sum of their measures is 180. 2 Two angles are complementary if the sum of their measures is 90. 3 You can write “the measure of angle 1” as m ∠1.

Are there any angles that are equal to one another?
In the above figure, 1 and 7, 2 and 8 are the pair of alternate exterior angles. Similar to alternate interior angles, even alternate exterior angles are equal to one another. Angles which are present in a similar position are known as corresponding angles. In the above figure, 1 and 5 are corresponding angles and they are equal to one another.
When are the measures of two angles complementary?
Two angles are complementary if the sum of their measures is 90. You can write “the measure of angle 1” as m ∠1. ∠1 and ∠2 are complementary, and m ∠2 = 32. Find m ∠ 1. m ∠1 + 32 = 90 Substitute 32 for m ∠2. m ∠1 = 58 Subtract 32 from each side. Are ∠1 and ∠2 are complementary, supplementary, or neither?
