| What is the triangle inequality theorum? | The sum of the lenghts of any two sides of a triangle is greater than the lenght of the third side. |
| Can a triangle be formed from the sides 10, 10, and 19? | yes |
| What is the side-side-side postulate? | If three sides of a triangle are congruent to three sides of another triangle, then the triangles are congruent. |
| What is the side-angle-side postulate? | If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. |
| What is the ASA postulate? | If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. |
| What is the AAS postulate? | If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent. |
| What is the HL postulate? | If the hypotenuse and a leg of one right triangle are congruent to the corresponding parts of another right triangle, then the triangles are congruent. |
| What is the perpendicular bisector theorem? | If a point is on the perpendicular bisector of a segment, then the point is equidistant from the endpoints of the segment. |
| An isosceles triangle has _ congruent sides. | 2 |
| What is a median of a triangle? | a segment from a vertex to the midpoint of the opposite side. |
