Transcript of Angles,types,interior and exterior points
Right angle
m/ PQR = 90°
A right angle measures 90°
An acute angle measure less than 90°
˂ 90°
OBTUSE ANGLES
An obtuse angle measures more than 90°
(˃ 90°)
The bigger angle is
The bigger angle is m /_UVW=110°
In the figure alongside, the points X, Y
,Z , K, L and M are on ˂ XYZ
The points L, M and N are in the Interior of the angle / ABC
EXTERIOR POINTS
The points X, Y and Z are points in the exterior angle of / ABC.
SUMMARY Right angle, acute angle and obtuse angle are the
three/3 types of angles.
Right angle measures 90°.(= 90° )
An acute angle measures less
than 90°.( ˂ 90°)
An obtuse angle measures
more than 90°.( ˃90° )
The points P, Q and R are in
the Interior of the ˂ ABC.
The points H, I and J are
points in the Exterior of ˂ ABC
EVALUTION
What is an acute angle?
What is the measure of right angle?
In the figure shown on the right
hand side, write the name of the
points that lie on the angle, in its
interior and in its exterior.
Points on the angle Points in the interior
of the ˂ ABC
Points in the interior
of the ˂ ABC
