Angles Side Relation
If the lengths of two sides of a triangle are unequal, the measures of angles of the opposite these sides are unrqual, the larger angle being opposite the longer side.

1- Angle Bisector
-
A point on the bisector of an angle if and only if the point is equidistant from the sides of the angle.
-
-
2- Median
A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid.

Congruent Triangles
Congruent Triangles. When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

Thales Theorem
If three or more parallel lines intersect two transversals, then they divide the transversals proportionally.
-
Pythagorean Theorem
In a right angled triangle the square of the long side is equal to the sum of the squares of the other two sides.
