Assignment 2. Classify Measure Angles
In the diagram below, angle seven equals 61° what is the measure of angle 8?
A.119°
Which of the angle pairs can be classified as vertical angles?
A.<3 and <1 D. <2 and <4
acute angle
An angle that measures more than 0 degrees but less than 90 degrees
obtuse angle
An angle that measures more than 90 degrees but less than 180 degrees
Find the angle indicated. angle 7 is equal to angle blank
Angle 1
Find the angle indicated. angle six is equal to angle blank.
Angle 4
Find the Angle indicated. angle three is equal to angle blank?
Angle 5
Find the angle indicated. angle two is equal to angle blank
Angle 8
Vertical angles
Angles that are opposite from one another at the intersection of two lines; vertical angles are congruent
If two angles are supplementary and one of the angles measure 38°, what is the measure of the larger angle?
B. 142°
If each of two complementary angles have the same measure, then each angle will equal blank
C. 45°
If if angle 1 and angle 5 are vertical angles in the angle 1 equals 55°, then angle 5 will equal blank
C. 55°
Two angles are adjacent, as shown in the diagram below. part a: Use complete sentences to describe the relationship between the adjacent angles. Part B: Make an equation to solve for X. Part C: Use your equation from part A and the value of X from Part B to prove your equation to be true for the adjacent angles in the diagram
Part A (describe their relation are the angles supplementary or complementary) Part B: 2x+68=180 2x=180-68 2x=112 X= 56° Part C: 2x+68=2x(56)+68 112*68=180
Two angles are complementary, As shown in the diagram below. Part A. Use the definition of complementary angles to set up an equation that can be used to solve the value of X. part B. Solve for the value of x.
Part A. X+15=90 Part B. X+15=90 X=90-15 X=75 degrees
Vertex
The point where two line segments, Lines, or rays meet to form an angle
Adjacent angles
Two angles that have a common vertex and side but are not overlapping
Supplementary angles
Two angles whose sum is 180°
complementary angles
Two angles whose sum is 90°
straight angle
an angle that measures exactly 180 degrees
right angle
an angle that measures exactly 90 degrees
