Question 1.
Are the two angles shown below supplementary?

Two angles are called supplementary when their measures add up to 180 degrees.
40 + 140 = 180 degrees
Hence the angles shown in the above figure is supplementary.

Question 2.
Are the two angles below complementary?

When the sum of two angles is equal to 90 degrees, they are called complementary angles.
25 + 65 = 90 degrees
Hence the angles shown in the above figure is complementary.

Question 3.
Are the two angles A and B supplementary?

Two angles are called supplementary when their measures add up to 180 degrees.
The sum of the two angles is 180 degrees.

Question 4.
Are the two angles supplementary?

Answer: No the angles are not supplementary.

Question 5.
Are the two angles CFD and DFE complementary? Why, or why not?

Answer: Yes, two angles CFD and DFE complementary. Because the sum of the two angles is complementary.

Question 6.
Name the two angles below, and determine if they are supplementary.

Two angles are called supplementary when their measures add up to 180 degrees.

Question 7.
Determine if the two angles are complementary.

When the sum of two angles is equal to 90 degrees, they are called complementary angles.
58 + 32 = 90 degrees
Hence the angles shown in the above figure are complementary.

Question 8.
What size angle would you have to add to make this a right angle?

Given angle = 30
Right angle = 90 degrees
30 + x = 90
x = 90 – 30
x = 60
So to make this a right angle we have to add 60 degrees.

Question 9.
In the figure below, list three sets of vertical angles.

There are two pairs of vertical angles with intersecting lines, they are across from each other.
∠2 and ∠4
∠1 and ∠3
∠3 and ∠5
∠4 and ∠6
∠6 and ∠8
∠5 and ∠7

Question 10.
Of the angles labeled below, which ones are supplementary?

∠5 and ∠2 are the supplementary angles.
Because the sum of two angles is 180 degrees.

Question 11.
List two pairs of vertical angles in the figure.

There are two pairs of vertical angles with intersecting lines, they are across from each other.
∠2 and ∠4
∠1 and ∠3

Question 12.
What type of angles are C and B?

∠C and ∠B are the supplementary angles.

Question 13.
List two pairs of vertical angles in the figure below.
