Part B: Using your knowledge of complementary, supplementary vertical, and adjacent angles, identify the pairs of angles named in each figure. For example, in Figure #1 you are to identify the supplementary angles, which are:

>AFC and >CFB

>AFD and >DFB

>CFB and >BFD

>BFD and >DFA

>DFA and >AFC

In figure #2, identify all of the vertical pairs of angles,

In figure #3, identify all of the complementary pairs of angles,

In figure #4, identify all of the vertical pairs of angles,

And so on for numbers 5-10.

 

It is angle and measures u and what the measure of and supplement and a complement

1. Solve for the missing angle measures.

Set 1 angles a and c are ? and are also ? Set 2 angles b and d are ? and are also ?

2.

set 1 angles a and c are ? set 2 angles b and d are ?

3.

angles a and b in both angles sets are ?

4.

Set 1 angle a = ?

Set 1 angle b = ?

Set 2 angle b = ?

Set 2 angle c = ?

5. Find the measure of each angle in the figure below.

Lines are named with the capital letter; angles are named with the lower case letter.

Angle a = ?

Angle b = ?

Angle c = ?

Angle d = ?

Angle e = ?

Angle f = ?

Two identical right-angled triangles, JKL
and MLK, overlap along side KL, as
shown. Sides JL and MK intersect at N.
The area of the overlapped region, 4KLN,
is equal to half of the area of 4JKL. The
area of the figure JKLMN is 48 cm2
. If
JK = 6 cm, determine the length of KL.
