In a trapezium (or trapezoid in American English), the opposite angles do not necessarily add up to 180 degrees. However, the consecutive angles between the bases of the trapezium do add up to 180 degrees. This means that if you take one angle from one base and the adjacent angle from the other base, their sum will equal 180 degrees.
What else can I help you with?
Do opposite angles in a parallelogram add up to 180?
No. Opposite angles are equal. Adjacent angles are supplementary.
How many angles trapezium?
A trapezium has 4 interior angles that add up to 360 degrees
What angles does a trapezium have?
A trapezium has 4 angles. The 2 adjacent angles are supplementary and the 4 angles together add up to 360 degrees.
What describes angles formed by 2 intersecting lines?
Opposite angles are equal. Adjacent angles add up to 180 degrees.
Is one side of the rhombus 180 degrees?
A rhombus has 4 interior angles that add up to 360 degrees and it has no right angles but opposite angles are equal.
What do angles in a trapezium add up to?
The internal angles add up to 360 degrees. If the trapezium has its base parallel to the top then the internal angles on the left of the parallel lines add to 180 degrees, the angles on the right add to 180 degrees.
Do opposite angles in a parallelogram add up to 180?
No. Opposite angles are equal. Adjacent angles are supplementary.
What shape has opposite angles that are supplementary?
A square or a rectangle has opposite angles that add up to 180 degrees
Do the opposite angles of a parallelogram add up to 180 degrees?
No.
Opposite angles of an inscribed quadrilateral are what?
Supplementary (they add to 180 degrees).
How many angles trapezium?

What angles does a trapezium have?
A trapezium has 4 angles. The 2 adjacent angles are supplementary and the 4 angles together add up to 360 degrees.
What describes angles formed by 2 intersecting lines?
Opposite angles are equal. Adjacent angles add up to 180 degrees.
If two sides in a triangle are congruent then their opposite angles are?
Their opposite angle are equal and all 3 angles will add up to 180 degrees
The opposite angles of a quadrilateral inscribed in a circle are?
The opposite angles of a quadrilateral inscribed in a circle are supplementary, meaning they add up to 180 degrees. This is due to the property that the sum of the opposite angles of any quadrilateral inscribed in a circle is always 180 degrees. This property can be proven using properties of angles subtended by the same arc in a circle.
What properties does a trampizium have?
A trapezium is a quadrilateral with at least one pair of parallel sides. The angles on the same side of a trapezium add up to 180 degrees. The lengths of the non-parallel sides can be the same or different.
What is the proof to show that sum of either pair of opposite angles in a cyclic quadrilateral is 180 degrees?
Because the 4 interior angles of any quadrilateral add up to 360 degrees and a cyclic quadrilateral diagonals opposite angles add up to 180 degrees therefore it follows that the other pair must be 180 degrees
