No. Opposite angles are equal. Adjacent angles are supplementary.
A trapezium has 4 interior angles that add up to 360 degrees
A trapezium has 4 angles. The 2 adjacent angles are supplementary and the 4 angles together add up to 360 degrees.
Opposite angles are equal. Adjacent angles add up to 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.
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.
No. Opposite angles are equal. Adjacent angles are supplementary.
A square or a rectangle has opposite angles that add up to 180 degrees
No.
Supplementary (they add to 180 degrees).
A trapezium has 4 interior angles that add up to 360 degrees
A trapezium has 4 angles. The 2 adjacent angles are supplementary and the 4 angles together add up to 360 degrees.
Opposite angles are equal. Adjacent angles add up to 180 degrees.
Their opposite angle are equal and all 3 angles will add up to 180 degrees
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.
The 4 interior angles of a trapezium add up to 360 degrees and if it's an isosceles trapezium it can have 2 equal obtuse angles and 2 equal acute angles
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
