A trapezoid is a 4-sided shape, therefore the sum of the angles adds to 360 degrees.
if you continue the lines until they touch you have a triangle, whose angles sum to 180 degrees.
using the law of sines, the ratio of length of a side to the sine of the angle opposite of a triangle is consistent for all three sides.
using the law of cosines you are able to find the angle between any two lengths of a triangle.
use these two laws to find the bottom two angles which form the base of the triangle.
the remaining two angles can be found by finding the angles in the triangle that sits on top of the trapezoid, and determining their compliment angle
180 - angle = compliment angle

Which quadrilateral can have four different angle measures?
Trapezoid
How do you find the missing angle measures of a regular trapezoid if one angle measures 50 degrees?
There is no such thing as a regular trapezoid. REGULAR implies that all sides and all angles are equal. If that is the case, with a quadrilateral each angle would be 90 degrees, none would be 50.
Which figure has 2 right angle 1 obtuse angle and 1 acute angle?
It fits the description of a trapezoid
Find the area of trapezoid ABCD All length measures are in centimeters?
"72.00"
Can a trapezoid have one right angle?
it doesn't normally but it can and still be a trapezoid
