when three sides are congruent to each

This is where two side pairs are congruent with a congruent pair of angles inbetween each side.

So Triangle BAC is congruent to Triangle YXZ E F G M N O Angle Side Angles is where there are two congruent angles and a congruent line pair inbetween.

So Angle EFG is congruent to Angle MON H I G J K L Angle Angle Side corresponding triangles

is where two triangles are congruent because

in order a pair of angles are congruent, a pair of angles are congruent, and then a pair of sides

that are congruent.

So Triangle GHI is congruent to Triangle JKL. Hypotenuse Leg is where two right angle

triangles are congruent to each other.

They are congruent because they both have 90 degree angles, one side must be congruent with its corresponding side, and another side must be congruent with its corresponding side.

So Triangle XYZ is congruent to Triangle LMN X Y Z L M N Three ways to tell if a pair of triangles are not congruent

1) If the corresponding sides are not congruent

2) If there is not enough information

3) If the order is Angle side Side or vice versa Block4-B
