TOPIC 1:Geometry-Angles and Triangles
.The sum of interior angles in a triangle=180 degrees
.Exterior angle=sum of the two opposite interior angles
.Types of triangles:
*Equilateral-all sides are equal,all angles 60 degrees
*Isosceles-two sides and two angles are equal
*Scalene-all sides and angles are different
Example Question:
Find the value of angle X in a triangle where the other angles are 45 degrees and
70 degrees.
Therefore; X=180 –(45+70)=65 degrees


TOPIC 2:Algebra-Simplifying algebraic expressions
*Combine like terms:
Example:3x+ 5x-2=8x-2
