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

How do you find the value of an angle in a trapezoid?
A trapezoid should add up to 360 degrees. add the angles that are shown and subtract by 360. the missing angle should be found.

How to Find the sum of the interior angle measures and the sum of the exterior angle measures of a quadrilateral?
360 degrees
How do you find the measures of a central angle?
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
What is the most amount of obtuse angle a trapezoid have?
A trapezoid can have a maximum of 2 obtuse angles. An obtuse angle is one that measures greater than 90 degrees. In a trapezoid, two of the angles are acute angles (less than 90 degrees) and the other two angles can be either acute or obtuse.
What is the missing angle measures of a trapezoid when one of the base angles is 78 and the other is 110?
The TWO (not one) missing angles are 102 and 70
How to find angle measures of a secant?
The "Far Arc Near Arc theorem" is used in finding the angle measures of a secant.
What a trapezoid with only 1 right angle?
a right trapezoid
Find the area of this trapezoid All length measures are in centimeters?
The area of a trapezoid is equal to the height, multiplied by the average of the two widths.
