5. a plane figure with three straight sides and three angles.
7. the angle between adjacent sides of a rectilinear figure.
8. corresponding parts of congruent triangles are congruent
10. having all its sides of the same length
11. two triangles where we know two sides and the included angle are equa
14. all the three sides of one triangle are equivalent to the corresponding three sides of the second triangle

1. the middle point of a line segment
2. the pair of matching sides that are placed at the same spot in two different shapes
3. identical in form
4. the longest side of a right triangle, opposite the right angle.

9. a line, ray, or segment that divides an angle or a line segment into two equal parts.
12. two angles and a non-included side of one triangle are congruent to two angles and a non-included side of another triangle
13. two angles and the side included between the angles of one triangle are equivalent to the corresponding two angles and side included between the angles of the second triangle
