  1. 3. angles that occupy the same relative position when two parallel lines are intersected by a transversal (a line that crosses them). When the lines are parallel, these angles are equal in measure.
  2. 7. ANGLE pairs of angles that are opposite each other when two lines intersect, and they are always congruent (equal in measure).
  3. 11. geometric shape defined as a closed, two-dimensional figure with three sides, three angles, and three vertices (corner points).
  4. 12. theorem states that if all three sides of one triangle are congruent (equal in length) to the corresponding three sides of another triangle, then the two triangles are congruent (identical).
  5. 14. PROPERTY if a = b and b = c, then a = c; essentially, if two things are equal to the same thing, they are equal to each other.
  6. 15. theorem states that if two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the two triangles are congruent.
  7. 16. SIDES is the side of a triangle or polygon that lies between two given angles, or the side common to two angles.
  8. 18. ANGLES an included angle refers to the angle formed between two adjacent sides of a shape, specifically a triangle or other polygon.
  9. 19. theorem states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

  1. 1. the external form, contours, or outline of someone or something
  2. 2. having the same shape and size, meaning two figures are congruent if they can be perfectly superimposed on each other, even after transformations like rotation, reflection, or translation.
  3. 3. Corresponding Parts of Congruent Triangles are Congruen
  4. 4. describes two lines, line segments, rays, or planes that intersect or meet at a 90-degree angle (a right angle).
  5. 5. one right triangle are congruent to the corresponding hypotenuse and leg of another right triangle, then the two triangles are congruent.
  6. 6. What is a final appearance image after a transformation
  7. 8. fact or piece of information that is accepted as true without requiring proof, forming the foundation upon which a proof or argument is built.
  8. 9. PROPERTY any geometric figure (like a line segment, angle, or shape) is always congruent to itself.
  9. 10. is not a valid congruence theorem for general triangles because knowing two sides and a non-included angle doesn't guarantee that two triangles are congruent; in some cases, multiple triangles can satisfy these conditions.
  10. 13. a definite or clear expression of something in speech or writing.
  11. 17. ANGLE an angle that measures exactly 90 degrees, formed by two lines or rays that are perpendicular to each other.
