trapezoid

quadrilateral with: 

• One pair of parallel sides. One pair not.
• The angles on either side of the bases are the same size/measure (congruent).

square

                                                                     

• quadrilateral wiht
• Four congruent sides with four right angles. Bisects each other they are parallel and they bisect.

Rhombus

• quadrilateral withOpposite angles of a parallelogram are congruents. A parallelogram with four congruent sides.

Isosceles acute

Obtuse Scalene


All triangles have 3 sides and 3 angles which always add up to 180°.

Acute Scalene
















In this instance, the orthocenter is located in the interior of triangle.

scalene right

it haves a right angle.
two unequal angles.
and no equal sides.

scalene obtuse

one of the angles is greater than a right angle- it is more than 90 degrees. an obtuse triangle might be isosceles or scalene.

scalene acute

an scalene triangle is one in whisch all sides have different lengths so all angles have different mesures..

     Suplementary Angles are to angles that the sum is 180
Complementary Angles are angles that sum to 90.  Ex. angles 1 and 2 in the video are complementary.
