An equilateral triangle has 3 equal interior angles that add up to 180 degrees
That depends on the shape of the trapezoid as for example if it is an isosceles trapezoid then it will have two equal acute angles and two equal obtuse angles that all add up to 360 degrees.
if it is a polygon then the total interior angles will equal 1080. so ear angle will be 135 degrees.
360 degrees.
The 4 equal angles of 90 degrees within a square add up to 360 degrees
An equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees.
A rectangle has 4 equal right angles of 90 degrees.
Exterior angles add up to 360 degrees Interior angles add up to 540 degrees
360
The interior angles in a quadrilateral (4 sided shape) add up to 360 degrees.
If the interior angles add up to 72000 degrees then the shape has 402 sides
A decagon will always have its interior angles measure 1480
A trapezoid's four interior angles equal 360 degrees
