a rhombus
No, two lines would not be parallel if the consecutive interior angles measured 108 degrees and 74 degrees. Consecutive interior angles on parallel lines are always congruent, meaning they have the same measure. Therefore, if the consecutive interior angles have different measures, the lines cannot be parallel.
triangle
A rhombus or a parallelogram
A rhombus or diamond.
The 3 interior angles are 90 degrees, 45 degrees and 45 degrees
All acute angles measure 50 degrees. All obtuse angles are supplementary to the acute angles, so they measure 130 degrees.
No, two lines would not be parallel if the consecutive interior angles measured 108 degrees and 74 degrees. Consecutive interior angles on parallel lines are always congruent, meaning they have the same measure. Therefore, if the consecutive interior angles have different measures, the lines cannot be parallel.
Each other of the alternate angles will measure 75 degrees because there are 180 degrees on a straight line.
Degrees are used to measure angles.
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.

64 degrees because the total of the angles has to equal 360 degrees for it to be a hexagon.
A rhombus or diamond.
They measure 105 degrees each.
Angles that measure less than 90 degrees are called acute angles. Right angles measure exactly 90 degrees and obtuse angles are greater than 90 degrees.
