Check the picture drawn
Consider the line segment AB,
let M be the midpoint of AB, so AM=MA
erect the perpendicular MT to AB from point M. Pick a point P on MT and join it to the points A and B
The triangles PMA and PMB are congruent from the Side Angle Side congruence postulate:
AM=MA, PM is common and m(PMA)=m(PMB)=90°, as MT is perpendicular to AB
so PA=PB

Answer:
The expression for c is
Step-by-step explanation:
The given equation is
To find an expression that represents,c we need to make c the subject.
Add b to both sides
We now divide both sides by 'a'
Simplify the LHS to get:
