Many things indeed. A cube or cuboid is a classical example, so is also a box, a door frame, even a tile on which you may stand. Any object whose lines cross or meet perpendicularly (right angle triangle), or whose faces meet at 90 degrees possess a right angle (cube).
a squarish "U"
A trapezium can have either no right angles or exactly 2 right angles: ...................................... ......------.........---------...... ..../........\.......|..........\..... .../..........\......|...........\.... ../............\.....|............\... ..-------------.....------------... ....................................... Are two trapezia: the first has no right angles, the second has 2.
there are no right angles in a rhombos, but there are 2 obtuse angles and 2 acute angles.
A hexagon has no right angles.
No. 2 right angles.
a pentagon :) only has 2 right angles
A Trapezium can have exactly 2 right angles.
two supplementary angles * * * * * NO! Supplementary angles sum to 180 degrees = 2 right angles. The correct answer is complementary angles.
gsgsf
2 right angles
It can have 2 right angles but not always
No, they have 4 right angles
A right trapezoid has at least two right angles.
