RAY
RAY
What is angle?
The two rays which
connect the line is
called angles.
ACUTE ANGLE
An angle whose measure is less than 90 degrees
is known as acute angle.
RIGHT ANGLE
An angle whose measure is 90 degrees is known
as right angle.
OBTUSE ANGLE
An angle whose measure is higher than 90 degrees but
less than 180 degrees is known as obtuse angle.
STRAIGHT LINE ANGLE
STRAIGHT LINE ANGLE
An angle whose measure is 180 degrees is known as
straight line angle.
COMPLEMENTARY ANGLES
Two angles whose measures add to 90 degrees
which form a right angle is known as
complementary angles.
SUPPLEMENTARY
ANGLES
SUPPLEMENTARY ANGLES
Two angles whose measures add to 180 degrees is
known as supplementary angles.
An angles have a common vertex and whose sides are
formed by the same lines is known as vertical
angles.
VERTICAL ANGLES
VERTICAL ANGLES
