Example Question #81 : Plane Geometry
Which is the greater quantity?
(a) The measure of an angle complementary to a angle
(b) The measure of an angle supplementary to a angle
It is impossible to tell from the information given
(a) and (b) are equal
(b) is greater
(a) is greater
(b) is greater
Supplementary angles and complementary angles have measures totaling and , respectively.
(a) The measure of an angle complementary to a angle is
(b) The measure of an angle supplementary to a angle is
This makes (b) greater.
Example Question #2 : Lines
and are complementary; .
Which is the greater quantity?
(A)
(B)
(B) is greater
It is impossible to determine which is greater from the information given
(A) is greater
(A) and (B) are equal
(B) is greater
Two angles are complementary if their degree measures total 90. Therefore,
Since , we can substitute, and we can solve for :
, making (B) the greater quantity.
Example Question #3 : Lines
Note: diagram is not drawn to scale
Refer to the above diagram. If , what is ?
and form a linear pair, so
Since , this can be rewritten as
, and the first equation can be rewritten as:
Example Question #82 : Plane Geometry
Note: Figure NOT drawn to scale.
Which of the following pairs of numbers could give the measures of and ?
None of the pairs given in the other choices is correct.
The two angles form a linear pair and therefore their measures total . We check all of the pairs for this sum.
The correct pair is .
Example Question #83 : Plane Geometry
Note: Figure NOT drawn to scale.
Refer to the above diagram. Which of the following triples could refer to the measures of , , and ?
All of the other responses are correct.
All of the other responses are correct.
The measure of an exterior angle of a triangle, which here is , is the sum of the measures of its remote interior angles, which here are and . Therefore, we are looking for the sum of the first two angle measures to be equal to the third.
All four triples satisfy this condition.
Example Question #7 : Lines
Note: figure NOT drawn to scale
The degree measure of is five degrees greater than twice that of . Which is the greater quantity?
(A)
(B)
It is impossible to determine which is greater from the information given
(A) and (B) are equal
(A) is greater
(B) is greater
(A) is greater
The degree measure of is five degrees greater than twice that of - that is,
Since and form a linear pair,
, and by substitution,
This makes (A) greater.
Example Question #8 : Lines
Note: Figure NOT drawn to scale
. What is ?
and form a linear pair and therfore, the the sum of their degree measures is .
Example Question #2 : Lines
Note: Figure NOT drawn to scale.
Evaluate .
, so
The measure of an exterior angle of a triangle, which here is , is the sum of the measures of its remote interior angles, which here are and .
