What is angle bisector?
In two triangles, if two pairs of congruent corresponding sides and the pair of corresponding angles between the sides are congruent, then the two triangles are congruent.
What is Side-Angle-Side Triangle Congruence Theorem?
One figure is _______ to another if there is a sequence of rigid motions and dilations that takes the first figure so that it fits exactly over the second.
What is similar?
The ratio (quotient) of the length of the adjacent leg to the length of the hypotenuse.

What is Corresponding Angle Theorem?
A sequence of translations, reflections, and rotations that take one shape to another congruent shape.
What is a rigid transformation?
In two triangles, if two pairs of corresponding angles, and the pair of corresponding sides between the angles, are congruent, then the triangles must be congruent.
