mar 1 congruent triangles activity
DESCRIPTION
A powerpoint for students to store the results of the their investigations using the gizmo "Proving Triangles Congruent" at www.explorelearning.com.TRANSCRIPT
Congruent triangles
Use the gizmo to investigate:
• For each slide, indicate whether or not two triangles are definitely congruent, or not necessarily congruent, under the given conditions, by highlighting either “definitely” or “not necessarily” on the slide
• If you choose “definitely”, paste several snapshots from the gizmo to support that
• If you choose “not necessarily”, paste one snapshot from the gizmo to support that
When two triangles have exactly one angle in common, they are (definitely, not necessarily) congruent
When two triangles have exactly two angles in common, they are (definitely, not necessarily)
congruent
When two triangles have exactly three angles in common, they are (definitely, not necessarily)
congruent
When two triangles have exactly one side in common, they are (definitely, not necessarily) congruent
When two triangles have exactly two sides in common, they are (definitely, not necessarily) congruent
When two triangles have three sides in common, they are (definitely, not necessarily) congruent
When two triangles have exactly one side and one angle in common, and the angle is adjacent to the side,
they are (definitely, not necessarily) congruent
When two triangles have exactly two sides and one angle in common, and the angle is not between the
sides, they are (definitely, not necessarily) congruent
When two triangles have exactly two sides and one angle in common, and the angle is between the sides,
they are (definitely, not necessarily) congruent
When two triangles have exactly two angles and one side in common, and the side is not between the
angles, they are (definitely, not necessarily) congruent
When two triangles have exactly two angles and one side in common, and the side is between the angles,
they are (definitely, not necessarily) congruent
