a cute little angle measures less than 90

ACUTE ANGLE

o

If the lines continued (crossed) you would say they are

INTERSECTING

OBTUSE ANGLE

a BIG FAT angle measures more than 90, but less than

180

oo

If the lines continued (crossed) you would say they are

INTERSECTING

RIGHT ANGLE

a right angle measures EXACTLY 90 o

If the lines continued (crossed) at 90 degrees; you would say they are

PERPENDICULAR

Parallel Lines

If the lines continued they would never intersect or cross~

think of the railroad tracks!
