1. In a plane if a line is perpendicular to each of the two lines then lines are perpendicular

2. If two altitudes of a triangle are congruent then the triangle is isosceles.

3. The sum of all angles of quadrilateral is 180o

4. Diagonals of a parallelogram form two congruent triangles.

5. Every angle is congruent to itself such congruence is called an identity congruent
