## Types of Angles

## Quadrilaterals

## Rectangle: Opposite sides are congruent : All 4 angles are right angles | ## Rhombus: Opposite sides parallel : All sides congruent : Opposite angles are congruent | ## Parallelogram: Opposite sides congruent : Opposite angles congruent : Opposite sides parallel |

## Finding Missing Angles for Quadrilaterals

If you have a trapezoid and the angles are congruent and you have an a,b,c,d.

If a,d is 105 and 75 degrees the other sides of the trapezoid would be the same and it would add up to 360 degrees

## Types of Triangles

## Equilateral Triangle: 3 congruent angles : 3 congruent sides | ## Isosceles Triangle: 2 congruent sides : 2 congruent angles | ## Scalene Triangle: 0 congruent sides : 0 congruent angles |

## Finding Missing Angles for a Trigales

If you a isosceles triangle and one angle is 50 degrees.

The other angles have to be the same congruent.

1. subtract 50 by 180 and you get 130

2. divide 130 by 2 and you get your answer witch is 65 degrees.
