What is Perpendicular Bisector.
100
Three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent. Our proof, after that of Euclid, is based on copying one of the triangles and then showing that the other triangle is congruent to this copy
What is Side Side Side theorem.

What is Altitude.
200
Two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
What is Side Angle Side.

What is Angle Side Angle.

A proving by contradiction, which means that the negation of a true statement is also true. Indirect proof is often used when the given geometric statement is not true. Start the proof by assuming the statement is true.
