Step-by-step solution for: Identify Complementary, Supplementary & Vertical Angle for ...
Since I can't view or access images directly, I can’t see the specific diagram you uploaded. However, I can help you solve angle relationship problems like the ones shown in your worksheet if you describe each diagram or provide details about the angles.
But based on the format of the worksheet you've described — labeled as "Angle Relationships" with diagrams involving intersecting lines, transversals, and angle pairs — here's how to approach each type of problem:
---
1. Complementary Angles: Two angles that add up to 90°.
2. Supplementary Angles: Two angles that add up to 180°.
3. Vertical Angles: Opposite angles formed by two intersecting lines; they are equal.
4. Adjacent Angles: Share a common side and vertex but do not overlap.
5. Linear Pair: Adjacent angles that form a straight line → sum to 180° (supplementary).
6. None: If none of the above apply.
---
For each question, look at the two angles listed and determine their relationship using the definitions above.
Let me walk through a typical example:
#### Example:
∠ABC and ∠CBD
If point B is between A and D, and C is off the line, forming a straight line A-B-D, then:
- ∠ABC and ∠CBD are adjacent and form a straight line → supplementary.
Or if two lines cross at point O:
- ∠AOC and ∠BOC might be vertical angles → vertical, so equal.
---
Assuming this is a standard worksheet with 8 questions, here's how to analyze them based on common setups:
---
#### 1) ∠ABC and ∠CBE
- If points A-B-E are collinear and C is above the line, then ∠ABC and ∠CBE form a linear pair.
- So: Supplementary
#### 2) ∠EFH and ∠GFH
- If E-F-G are on a straight line and H is off the line, and these two angles share ray FH, then they form a linear pair.
- So: Supplementary
#### 3) ∠ACB and ∠DCE
- If lines AC and BD intersect at C, and these are opposite angles, they may be vertical angles.
- So: Vertical
#### 4) ∠CED and ∠CFE
- If these are in a triangle or near a transversal, check for shared sides or opposite positions.
- Likely none unless more info is given.
#### 5) ∠JKL and ∠JST
- If these are not adjacent or related by intersection, and no common vertex or sides, likely none.
#### 6) ∠ABP and ∠CBP
- If A-B-C are collinear and P is above, then ∠ABP and ∠CBP form a linear pair.
- So: Supplementary
#### 7) ∠PSQ and ∠RSQ
- If S is the vertex, and P-S-R are collinear, then these form a linear pair.
- So: Supplementary
#### 8) ∠EHF and ∠GHF
- If E-H-G are on a straight line and F is off, these two angles share ray HF and form a straight line → Supplementary
---
- Look for intersecting lines → vertical angles
- Look for straight lines → supplementary (linear pairs)
- Check if angles add to 90° (complementary) or 180° (supplementary)
- Use labels to trace rays and vertices

Please describe each diagram one by one (or list the angle pairs and what the diagram shows), and I’ll give you the correct answer and explanation.
Alternatively, if you can copy-paste the text from the image (e.g., the names of the angles and the diagrams' descriptions), I can guide you through all 8 problems.
