Math Recap

Angles inside triangles

Angle Relationships

Transversal lines

Parallel lines

the angles should all add up to 180

Equilateral triangles should have the same number for each angle

you don´t need a protractor to find the angles

there can only be one obtuse angle in a triangle

there can only be one right angle

there is allowed to be 3 acute angles in a triangle

Parallel lines never touch

To tell if parallel lines are equal make it a transversal lines

if its a parallel line then the interior angles will be the same and so will the exterior angles

parallel lines are congruent

there are angles shaped as letters like z angles and f angles

a transversal line is a line that intersects with other lines

Transversal lines help determine if two lines are congruent

Transversal lines are only needed to determine if two lines are congruent

Supplementary angles are two angles that have a sum of 180

supplementary angles can help determine the rest of the angles

Supplementary angles can only have 2 angles as the sum of 180 if 3 or more angles add up to 180 they are not considered as a supplementary angle

Whenever two parallel lines are cut by a transversal two interior angles on the same side of the transversal turn into a supplementary angle
