Angles
obsute angles
angle has a mesure that lies between 90 degree is calleducate angles
90<a<180
Straight angles
angle has a measure that is exactly 180 degree is called straight angles
a=180
right angles
angle has a measure which is exactly 90 degree is called right angles
a=90
acute angles
angle has a measure than 90 degree is calledacute angles
a<90
zero angle
is that two lines or two rays are in the same direction as a common point called the vertex. An angle is made up of two rays connected end to end at a common point
a=0
angles
two rays that have same initial point forms an angle. this initial point is a called vertex and the union of the rays are called angles
plane and spaces
a plane is a flat surface witch extends infinitely in all directions
corresponding angles
corresponding angles are formed where a line known as an interesting diagonal crosses a pair of straight lines, correspondin angles are pairs of angles that are in the same relative position at different intersections
vertically opposite angles
angles formed by two lines that are opposite and interest at a given vertex
supplemantary angles
a pair of two angles is supplementary when their sum is 180 degrees. each one is called the supplement of the other
complementary angles
a pair of two angles is complementary when their sum is 90 degrees, each one is called complement of the other
reflex angles
angle has measure lies between 180 degree and 360 degree is called reflex angle
complete angle
angle has a measure that is exactly 360 degree is called complete angles
180<a<360
a=360
adjacent angles
the angles that have a common arm are called adjacent angles
line segment
a line segment is a part of a line between
line
a line is set of points in a straight past that extends in opposite directions without ending
point
a point Is an exact position on a plane surface
