Description
CONGRUENCY OF TRIANGLES
MIDPOINT THEOREM
Midpoint theorem states that, the line joining the midpoints of two sides of a triangle is parallel to the third side and half of the length of the third side
In △ PQR, S and T are the midpoints of side PQ and PR
∴ ST || QR
And, ST = 1/2 QR
Converse of midpoint theorem states that if a line is drawn through the midpoint of one side of a triangle, and parallel to the other side, it bisects the third side
In △ PQR, S is the midpoints of side PQ and PR, and ST || QR
∴ ST = 1/2 QR
and, T is the midpoint of side PR
Equal Intercept Theorem states that if equal intercepts are made on three or more parallel lines by a transversal, then the intercept made by any other line on these lines will also be equal.
