Angle Sums:

Name | Type | Description | Funsheet | Key | Standard | Key |

Complementary Angles | Riddle | Students will find the missing angle given the angles are complementary. All angles are integers. | ||||

Supplementary Angles | Riddle | Students will find the missing angle given the angles are supplementary. All angles are integers. | ||||

Supplementary Angles 2 | Riddle | Students will find the missing angle given the angles are supplementary. All angles are decimals to the tenths place. |

Congruent Figures:

Name | Type | Description | Funsheet | Key | Standard | Key |

Congruent Shapes Matching | Riddle | Students will match congruent figures. Closed figures only (NO segments, angles, etc.) |

Line of Symmetry:

Name | Type | Description | Funsheet | Key | Standard | Key |

Symmetry Art | Standard | Given a shape and line of symmetry, student will complete other half of drawing. |

Parallel and Perpendicular Lines:

Name | Type | Description | Funsheet | Key | Standard | Key |

Interior, Exterior, Vertical or Corresponding | Standard | Students will identify angles as alternate interior, exterior, vertical or corresponding | ||||

Parallel Lines and Transversals 1 | Standard | 5 figures, 20 questions. Identify angles formed by a transversal. | ||||

Parallel Lines and Transversals 2 | Riddle | Solve for x, all angles are congruent. Two-step. | ||||

Parallel Lines and Transversals 3 | Riddle | Solve for x, all angles are congruent. Variables on both sides. | ||||

Parallel Lines and Transversals 4 | Riddle | Solve for x, all angles are supplementary. Variables on both sides. | ||||

Parallel Lines and Transversals 6 | Riddle | Solve for x, angles are either congruent or supplementary. |

Points Lines Planes Angles:

Name | Type | Description | Funsheet | Key | Standard | Key |

Points, Lines, Planes and Angles | Standard | 5 figures, 20 questions. |

Polygons:

Name | Type | Description | Funsheet | Key | Standard | Key |

Drawing Polygons | Activity | Students will draw polygons from triangles to decagons on geoboard dot paper. | ||||

Hidden Polygons | Activity | Funsheet is triangle grid, standard is isometric dots. | ||||

Quadrilateral Venn Diagram | Venn Diagram | Figures can be cut and glued into correct place in Quadrilateral Venn Diagram. |

Triangles:

Name | Type | Description | Funsheet | Key | Standard | Key |

Sum of Triangle Angles | Riddle | Given 2 angles, students will find the missing angle. All integer angles. | ||||

Sum of Triangle Angles 2 | Riddle | Given 2 angles, students will find the missing angle. All decimal angles (tenths place). | ||||

Sum of Triangle Angles 3 | Standard | Students must recognize isosceles and right triangles (all angles not explicitly given) to find the value of x. All integer angles. | ||||

Sum of Triangle Angles 4 | Standard | More complex, as students must now "solve for x." Ex. 2x + (x+1) + 80 = 180. |
