If the two sides which are not parallel have equal lengths, then the trapezoid is called an isosceles trapezoid (standard trapezoid has unequal sides). The base angles in an isosceles trapezoid are equal in measurement, also I know that a trapezoid with two nonparallel sides the same length is called an isosceles trapezoid.
No, not every trapezoid is an isosceles trapezoid.
The sum of the angles in a trapezoid is 360 degrees, therefore, the forth angle in this problem is: 360 - (60+120+80) = 100 degrees
The altitude of a trapezoid bisects the bases of the trapezoid.
All the names to classify a trapezoid are a trapezoid and a quadrilateral.

It need not be.
1/2
The answer is 1/3.
one third your welcome
A trapezoid has one height: vertical measurement from top to bottom, and two bases: horizontal measurement on top and horizontal measurement on bottom. To find the area, you add the two bases together, multiply that by the height, and then divide by 2.
2 and 1 half

The whole measurement of a angle.
