How many of these 30Β° angles will fit together to make a straight line?
there are 4 right angles as 1 right angle is 90 degrees and 90 x 4 = 360
A square has 4 right angles.
4 right angles
1 complete rotation = 360o 1 right angle = 90o 360o ÷ 90o = 4 There are 4 right angles in 1 complete rotation.
Perpendicular lines make four 90 degree angles otherwise known as right angles.
four
There can be 0 to 5 right angles, or 1 to 6 obtuse angles in a hexagon.
12
4 right angles, no other angles.
1
Two right angles add up to 180 degrees because a right angle is 90 degrees
A square and a rectangle are two of them because they both have 4 interior right angles
None - the edge is curved so no straight sections to make angles
Just one of them and two acute angles that add up to 90 degrees.
