Calculators Allowed
Problem 1 Vertical Angles
75° x + 25
Rule: Opposite angles are EQUAL!
Set both sides equal to each other.
x + 25 = 75
x = 75 − 25 =
x = _____ [1] Pumpkin Orange
Problem 2 Straight Line Angles
120° x
Rule: Straight line adds to 180°!
Subtract 120° from 180°.
120° + x = 180°
x = 180° − 120° = °
x = _____° [2] Midnight Purple
Problem 3 Right Angle (90°)
55° x
Rule: Right angle adds to 90°!
Subtract 55° from 90°.
55° + x = 90°
x = 90° − 55° = °
x = _____° [3] Slime Green
Problem 4 Triangle Angles
50° 85° x
Rule: Triangle 3 angles add to 180°!
Add 50 + 85 = 135°, then subtract.
50° + 85° + x = 180°
x = 180° − 135° = °
x = _____° [4] Vampire Red
Problem 5 Z-Shape Angles
110° 2x
Rule: Alternate interior angles are EQUAL!
Divide 110° by 2 to solve for x.
2x = 110°
x = 110° ÷ 2 =
x = _____ [5] Moon Yellow
Problem 6 Isosceles Triangle
100° x x
Rule: Two equal sides = EQUAL bottom angles!
Leftover 80° is split evenly in half.
180° − 100° = 80°
Base Angle x = 80° ÷ 2 = °
x = _____° [6] Ghost Silver

Step-by-Step Solutions & Color Key 6 High-Success Core Problems
| # | Core Geometry Rule | Scaffolded Algebraic Calculation | Target Value | Color Code |
|---|
| 1 | Vertical Angles (Equal) | x + 25 = 75 \(\implies\) x = 75 − 25 = 50 | x = 50 | [1] Pumpkin Orange |
| 2 | Straight Line (Adds to 180°) | 120° + x = 180° \(\implies\) x = 180° − 120° = 60° | x = 60° | [2] Midnight Purple |
| 3 | Right Angle (Adds to 90°) | 55° + x = 90° \(\implies\) x = 90° − 55° = 35° | x = 35° | [3] Slime Green |
| 4 | Triangle Sum (Adds to 180°) | 50° + 85° = 135°. x = 180° − 135° = 45° | x = 45° | [4] Vampire Red |
| 5 | Alternate Interior (Equal) | 2x = 110° \(\implies\) x = 110° ÷ 2 = 55 | x = 55 | [5] Moon Yellow |
| 6 | Isosceles Base (Equal) | 180° − 100° = 80°. Base angle x = 80° ÷ 2 = 40° | x = 40° | [6] Ghost Silver |
♿ Targeted IEP & 504 Accommodations
- Calculation Scaffolding: Allow 4-function calculators for subtraction from \(180^\circ\) and \(90^\circ\) to isolate geometric reasoning from arithmetic barriers.
- Color Highlighters: Have students highlight the two vertical angles or the Z-shape in yellow before writing equations to reinforce visual recognition.
- Read-Aloud Support: Read the rule strips aloud ("Opposite angles are EQUAL", "Straight line adds to 180°") during the initial 5-minute modeling block.
