LINES AND ANGLES
TYPES OF TRIANGLE
BASIS OF SIDES
Scalene (all sides diff)
Isoceles (2 sides are equal)
Equalateral(all sides are equal)
PROPERTIES
Sum of the interior angles of traingle =180degree
Angle BOC=90+1/2 angle A
Ext. angle +Sum of 2 interior opp. angles
BASIS OF ANGLES
Right =90 degree
Acute=0<90degree
Obtuse (90degree<0<180degree
Angles made by transeval
1. Corresponding angles = angle-2,5;2,6;3,7;4,8
Alternate interior angles=angle 1,7;2,8
Co-interior angles=angle1+angle8=180degree=angle2+angle7
Alternate exterior angle angle4,angle6;;angle3,angle5
