When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
Perpendicular lines or parallel lines are two examples
It has 1 set of 3 parallel lines and 3 sets of 2 parallel lines, and 18 angles (3 sides meet at each vertex)
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
straight angles
A trapiziod
It is called a trapezium.
Parallelogram
I think it is when there are 2 parallel lines, then the lines which cut both is called transversal.so, the angles which are between one side of the transversal and a parallel line must be called a transversal angles.
A trapezoid 2nd answer: Also known as a trapezoid figure, or just trapezoid.
with 2 right angles?....I'm not sure that this type of shape is possible...
When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
It is the transversal line that cuts through parallel lines creating alternate equal angles.
paralellogram
Trapezoid
Providing that the two lines are parallel then they are called corresponding angles.
A shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.
